Abstract
The invention discloses a low-vibration motor comprising a frame and a stator core disposed inside the frame. The two ends of the stator core are each equipped with a vibration isolation device. Each vibration isolation device includes an end pressing plate arranged at one end of the stator core and vibration isolation plates connected to the bottom side of the end pressing plate, the vibration isolation plates are fixedly connected to the bottom plate of the frame, and the end pressing plate and the vibration isolation plates are in a clearance fit relationship. The axis of the stator core and the frame is adjusted by a gasket. The stator core only contacts the bottom plate of the frame and does not contact wall plates. The vibration transfer path of the stator coil is simplified. The stator core of the motor is mounted in the motor frame through the vibration isolation devices. Thus, the stator core is hoisted into the frame from the upper part of the motor (with the upper cover plate of the motor frame cancelled directly), which is different from a conventional motor of which the stator core is axially mounted on the two wall plates in the middle of the frame through an end cover. Vibration is transferred to the bottom plate of the frame after being isolated by the vibration isolation plates, and is then transferred to the bottom pins of the motor, so that vibration is reduced greatly.
Description
Technical field
The invention belongs to technical field of motors, be specifically related to the motor of a kind of occasion being suitable to the running environment low vibration of requirement, be particularly suitable for making warship Marine Propulsion Motor.
Background technology
The design of low vibrating motor is carried out the work with optimization bang path two aspect mainly around reducing motor energization source size.Wherein motor is by adopting the electromagnetism optimization such as skewed slot, rational slot fit to weaken electro-magnetic exciting force, thus reducing the vibration of motor foot；Bang path optimization, mainly through carrying out vibration characteristics and the design of exciting force characteristic harmony of motor, optimizes bang path, increases damping and reduce the exciting force transmission to motor foot.
The Comparision that the employing electromagnetism optimization of current motor reduces electro-magnetic exciting force is many, and the basic footing manufacturing out at motor for motor of carrying out of bang path Optimization Work increases vibroshock, reduces the exciting force impact on mounting feet.
And conventional motor electro-magnetic exciting force can be transferred directly on electric baseboard by end clamp plate, and can be transferred on electric baseboard by the side plate of support, end cap, bearing etc., couple more, control difficulty.
Summary of the invention
In order to overcome the shortcoming and defect of prior art, the invention provides a kind of low vibrating motor, it is an object of the invention to oriented control electro-magnetic exciting force bang path, by arranging vibration isolation plate at motor internal, be substantially reduced the vibration of motor.
The technical solution adopted for the present invention to solve the technical problems is: a kind of low vibrating motor, including support and the stator core being positioned at support, described stator core two ends are provided with isolation mounting, described isolation mounting includes the end clamp plate being arranged on stator core one end and the vibration isolation plate being connected to end clamp plate bottom surface, described vibration isolation plate is fixedly connected on the base plate of support, it is matched in clearance between end clamp plate and vibration isolation plate, adopts pad to adjust the axis of stator core and support.
The low vibrating motor of described one, its vibration isolation plate has four, is separately positioned on the two ends of end clamp plate bottom surface.
The low vibrating motor of described one, the cross section of its end clamp plate is " ┻ " font.
The low vibrating motor of described one, its end clamp plate and vibration isolation plate are bolted.
The base plate of the low vibrating motor of described one, its vibration isolation plate and support is bolted.
The low vibrating motor of described one, its vibration isolation plate, bolt and pad all adopt vibration isolation damping material.
The invention has the beneficial effects as follows: stator core only contacts with the base plate existence of support, contactless with wallboard, simplify the vibration transfer path of stator core, motor stator core is installed in electric machine stand by this isolation mounting, when such stator core is installed, it is different from generally conventional motor and is axially mounted on middle two wallboards of support through end cap, but directly cancel electric machine stand upper cover plate, by in motor top lifting to support, vibration is transferred on frame bottom plate after vibration isolation plate vibration isolation, it is transferred to again on motor foot, is substantially reduced.
