Description
Technical field
The utility model relates to a kind of brake motor, especially a kind of Compound cage solid rotor soft-start brake motor.
Background technology
In the travelling mechanism of handling machinery, motor normally starts under loaded-up condition, and the existing used brake motor of hoisting machinery is large because of starting torque, when starting and stopping, impacting large, to hoisting heavy potential safety hazard large (such as the allocation and transportation of cast steel, ladle etc.), motor itself and hoisting machinery are impacted large its useful life that affects, and the research and development soft-start brake motor becomes handling machinery braking motor designer's common recognition and target.
Why soft-start brake motor can realize " soft " starting, and its key is on the rotor structure of motor.The rotor of soft start motor adopts the good mild steel solid rotor of magnetic property, the rotor core surface in the induced field that stator produces by the kelvin effect effect, form " eddy current " and form rotor circuit, this rotor circuit produces the induced current of rotor under the induced field that stator produces and since closed energized conductor in magnetic field, produce electromagnetic force, just export electromagnetic torque, make the motor rotation.
The solid rotor of the first generation soft start motor of domestic development is without the sliver structure, and the solid rotor surface does not have grooving; The braking of motor is to add solenoid and spring braking sheet in rearward end, and solenoid is switched on, brake(-holder) block is thrown off mutually during work, and restraining coil outage, spring force promote to make brake(-holder) block pressing, motor brake during shutdown.
The development of my company second generation solid rotor soft-start brake motor---a kind of its rotor of composite rotors soft-start brake motor is composite construction, front 2/3 part of this rotor is still for vertically to cut skewed slot, surface eddy is divided into a plurality of minizones without sliver structure, rotor surface, in order to reduce the impact of eddy-current heating; Rear 1/3 part is made to have the separation trough that cuts from the end and is cut apart ring, adopts pressure casting method die casting to enter the aluminium material, make it to form the end-enclosed loop at separation trough in the ring with cutting apart; The braking of motor is at spring braking dish of motor shaft suit, cooperates the formation brake with brake(-holder) block on the rear end cap, behind electrical power, the rotor front portion is still the same with first generation soft start motor to produce electromagnetic torque and makes motor rotation, the rear portion then produces axial electromagnetic force under the effect of stator coil, make brake disc overcome that spring force and brake(-holder) block are thrown off, the motor rotation, other magnetic force disappears thereupon after the outage, the spring braking dish under spring-force driven dual with the brake(-holder) block pressing, motor brake, rotor stops the rotation.Solid rotor soft start motor is updated through second generation machine, performance has obtained the raising of essence, and its outstanding advantages is: starting current is little, starting torque is large, starting time transitional period is compared the mouse-cage electric captain, the slippage large impact is little, overload capacity strong, stall 5min motor does not burn, be fit to the Fraquent start operating mode; Start with traditional modes such as external connected electronic soft initiator, variable frequency starting and variable resistance of passing through and to compare, this soft-start mode need not add plug-in design, motor manufacturing expense and crane configuration expense reduce greatly, and structure is light and handy, install, debug, safeguard very convenient, therefore failure rate is low is approved rapidly in the short period of time and is promoted the present main flow motor that has become travelling mechanism in the hoisting machinery.But second generation machine also exists apparent in view shortcoming: namely power factor is low, efficient is low.Because the revolutional slip of solid rotor motor large (more much bigger than squirrel-cage motor), when reaching rated power, its output torque also reaches rated value, but the revolutional slip of motor is large at this moment, and rotating speed is also lower.User's reflection: the soft start motor is when operation " weak "---and operation is weak.
For the problems referred to above, my company researches and develops again successful third generation solid rotor soft-start brake motor---a kind of Compound cage solid rotor soft-start brake motor, this third generation machine had both kept the soft start characteristic of first, second machine in generation, this motor is exerted oneself constant, even when steady operation---" energetically " becomes it to have concurrently the motor of " soft " starting and " firmly " operation characteristic.This kind Compound cage solid rotor soft-start brake motor can be used as the power of cart, wheeling mechanism and the electric block walking mechanism of various single-beam cranes, double girder crane, gantry crane, also can be used for environmental protection equipment, metallurgical machinery, mining machinery, ship machinery, harbour machinery, chemical machinery and automobile making, industrial production line etc. and need the field of continuous operation, application prospect is very wide.
According to retrieval, at home and abroad there is no the patent application identical with the utility model.
