  • the disclosure concerns a an equipment for utilizing drive end flange mounted electrical motors, mainly referring to international mounting (IM) codes IM B5 (large flange mounting, also known IM 3001 mounting) and IM B14 (small flange mounting, also known IM 3601 mounting), but not limited to these, in a steerable application without strict need to use special formed electrical motor.
  • IM international mounting
  • the disclosure may be used together with ship design including pulling propeller design with fixed pitch blades, in steerable underwater application.
  • the disclosure may be used together with underwater energy generation application, with reactive steering by water flow direction or by another steering application.
  • the disclosure may be used together with any other steerable electrical motor application in moist or wet conditions.
  • the disclosure may be used together with variable types of electric motors available on the market, with minor requirement to modify the industrial standard flange mounted motor design.
  • the disclosure may be used together with single or two bearing electrical motor designs.
  • the disclosure may be used in adaptive manner together with varying length and diameter of electrical motor, mainly considering drive end flange diameter up to SAE B5 M 660mm for frame size 315 electrical motors, but not limited to this, carried from the drive end flange.
  • the unit may be supported from non-drive end of motor with modifiable element, providing self-supporting installation against forces generated by ship movements and steering actions in the water.
  • the disclosure concerns a shafting between electrical motor and propeller.
  • the disclosure concerns utilization of flange mounted water-cooled, oil-cooled, oil-immersed or air-cooled electrical motor designs.
  • the disclosure concerns the motor and shaft support structure and equipment, which allows flange mounted electric motor dimension variants to be used with the same structural mounting interfaces and simultaneous control of the steering direction of the shaft while electrical motor is operated.
  • Such variants may be in the motor length, diameter, weight, shaft end design, additional sealing systems, pressurization, cooling type or in-line reduction gear installation (also geared solution with full or hollow shaft are applicable).
  • the disclosure concerns steering element that is allowing variants to the motor dimensions and weight.
  • the disclosure concerns a structure, that is externally steered by steering system or by water movement.
  • Disclosure is presenting main components connected in one or two ends of electrical motor. When connected to together in assembly order ( figure 1 ), these create a L- or D-shape, self-supporting structure, with possibility to use different variants of the electric motor type or size, within the limits defined by the design.
  • FIG. 1 Electrical motor is selected (line A, two types presented). Motor is flange mounted (line B) to the DE channel piece, which is providing standard SAE flange interface. NDE channel piece is flange connected (line C, long and short motor design presented). Depending the motor dimensions and forces defined by the vessel operation, this may be connected either directly to motor stator frame or to the DE channel piece as a cover hood and routing for main cables. In more demanding installations, rudder element (line D left) is separately flange connected to NDE channel piece. This is made to the correct dimensions and spring loaded downwards (line E left) and locked to DE channel piece by welding. Element forms a steering lever distributor for external steering pistons or wire. In smaller units the steering lever may be connected onto the DE Channel pipe. Propeller shaft unit is applied on the forward side, utilizing flange connection to DE channel piece and accommodates shaft connection according to motor design.
  • FIGURE 1 A first figure.
  • This self-supporting L-shape or D-loop is installed through the ship's hull connector or directly through ship's hull structure. This penetration interface requires to be designed against pending forces, weight carrying and lifting forces.
  • the said L-shape or D-loop is steerable by external steering manners familiar from traditional rudder steering or from outboard motor steering ( figure 2 presenting available steering angles for D-shape unit).
  • Connection pieces WHITE
  • Length L defines the steering lever and allows steering force minimization.
  • Electric motor flange connections and protection hood flange, motor stator frame ends or electric motors end shields of said D-loop are made watertight by means of usual ship-building methods, such as sealed bolted flange connections (fine machined surfaces, O-rings and sealing material, tighten in design torque). From propeller direction, unit is water-tight by shaft sealing lip systems. For the additional safety against leakage, unit may be monitored by level switches and suction pipes or pressurized.
  • Said L-frame and D-loop may be utilized as a single confined space when electrical motor end shields are having openings, as presented in the figure 3A . This could be the case when air forced cooling is required for the electrical motor cooling. In case electrical motor end shields are closed and additional shaft sealing is considered, the D-loop contains three main spaces, as presented in the figure 3B . Cable connection, cooling piping/flexible piping and sensor wiring to the ship and cooling media distribution to/from ship are made via the channels provided by said "DE channel piece" and said "NDE channel piece".
  • DE channel pipe flange connection (6) is connected to DE channel pipe flange connection (6) with bolted connection. Flange water tightness is secured by O-ring and sealing silicone. Propeller side of the DE channel pipe flange (5) is pre-pared for the shaft lip sealing system and shaft protect elements. Air space inside DE channel pipe may be pressurized against leakage, through Connection piece (10).
  • Non-drive end (NDE) of the motor is connected to the NDE Channel piece (7) utilizing the connection location of the fan cover (3) and additional bolting.
  • Motor cables, that are coming from NDE, above Cooling air blower (2) are guided to the channel pipe (11) from where they are led to the ships side via watertight flexible ducting. Cooling air is either delivered through this pipe (11) or through the DE channel unit pipe (4), from where this is ducted to the vessel side through the connection piece (10). Forced air fan may be located also on the ship side.
  • NDE-support element with rudder surface is bolt connected onto the rudder side flange (9) interface of the NDE channel piece.
  • Form and rudder steering surface may be modifiable according to the application and strength dimensioning of the installation.
  • Figure 6 presents installation for Electrical motor type B, where water-jacket cooled type permanent magnet synchronous motor (12) is selected.
  • Motor is of length L2 and of diameter d2. Motor is equipped with cooling water plugs (13) that are in the stator frame. Additional thrust 5 bearing element (14) is added.
  • DE channel pipe (15) has two additional bushings (16) for cooling water circulation that is done from the vessel side.
  • Motor cooling circuit is connected to these and protected with hydrodynamically shaped cover.
  • Non-drive end (NDE) of the motor is connected to the NDE Channel piece (19) utilizing the connections in the thrust bearing element (14).
  • Motor cabling, that is coming from NDE, above thrust bearing is guided to the channel pipe (19) from where they are led to the ships side via watertight flexible ducting.
  • NDE-support element with rudder surface is bolt connected onto the rudder side flange interface of the NDE channel piece.
  • Form and rudder steering surface may be modifiable according to the application and strength dimensioning of the installation.
  • Connection piece (17) is welded onto the position 20 slot of the DE Channel pipe (15). Welding seam is made around the piece and onto the full distance, both sides and end, across NDE sup-port element (20). Strengthening bars (18) are added onto NDE support element (20). Welding seam is made full distance, both sides and end, across the NDE support element (20).
  • FIG. 7 presents the connection of the Propeller cone (1), including the propeller shaft (2) and propeller connection interface (3).
  • Shaft end (motor end) is designed according to electrical motor shaft, either cylindrical with key(s) or DIN Spline, which are providing practical installation possibilities. There is sufficient axial clearance in the joint, which prevents propeller axial forces to be delivered from Propeller Cone to electric motor rotor.
  • Shaft is supported by roller bearings (4) and axial movements are transferred to structure by two-directional thrust bearings (5), which also holds the shaft and propeller from moving in either axial direction.
  • Propeller end is designed according to standard propeller connection (6) options.
  • shaft mechanical sealing (7) which may include emergency inflatable element.
  • Leakage to the structure may be measured from unit bilge (8) by level sensors and by suction pipes.
  • Figure 8 presents underwater power generation installations options, which are demonstrating the possibility to install steerable unit standing up or hanging down, keeping the steering ability according to self-guided orientation to the water flow.
  • Disclosure is presenting the technical solution of utilizing flange mounted main components to form a self-supporting structure, which allow utilization of wide range of existing components in the market and their use in the underwater steerable unit.
  • main elements of disclosure When main elements of disclosure are connected to together, these create a dry-channel self-supporting L-shape or D-loop structure, with possibility to use different variants of the electric motor type or size, cooling, feedback or manufacturer at moist, wet or underwater conditions.
  • Structure provides a possibility to have steering surface and steering control interfaces for utilization as ships propulsion or underwater power generation unit.
