Abstract
A variable-frequency adjustable-speed asynchronous traction motor of an electric wheel dump truck comprises a left end cover, a rotor, a stator, a speed sensor and a right end cover. A hole is formed on the left end cover, the three-phase power source wire of a motor penetrates the hole of the left end cover to lead out, the two ends of the iron core of the stator are compressed through a pressure plate and a guide strip on the rotor is directly welded with an end ring; and the speed sensor is mounted in the engine seat of the motor and fixed on a right end cover. The asynchronous traction motor has the advantages of simple structure, reliability in work and easiness in maintenance, and fully meets the requirements on the traction motor of the electric wheel dump truck of a mine communication driven system.
Description
Technical field
The utility model relates to a kind of traction motor, especially relates to the variable-frequency control asynchronous traction motor of a kind of electric power wheel self-discharging vehicle.
Background technology
Because mine conditions is poor, keep in repair, safeguard very inconvenient.Various plant equipment that demand can be easy to maintenance even non-maintaining more and more.
Existing mine electric power wheel self-discharging vehicle requires the commutator that is provided with variable-frequency control asynchronous traction motor because of commutation, and structure is complexity, manufacturing and difficult in maintenance, and in use often cause ring fire easily and burn out motor.
The utility model content
It is a kind of simple in structure that the purpose of this utility model is to provide, and volume is less, and reliable operation is safeguarded the variable-frequency control asynchronous traction motor of simple electric power wheel self-discharging vehicle.
The purpose of this utility model is achieved through the following technical solutions: it comprises left end cap, rotor, stator, velocity transducer, right end cap, has aperture on the left end cap, and the three-phase power line of motor passes the aperture of left end cap and draws; The iron core two ends of stator compress by pressing plate; Direct and the end ring welding of epitrochanterian sliver; Velocity transducer is installed in the support of motor, is fixed on the right end cap.
Temperature sensor is installed on the pressing plate, can monitors the temperature rise of motor by temperature sensor in real time.
The air opening end of motor is provided with deep bead, and described deep bead can put together limited air quantity, avoids wind to spread everywhere, is beneficial to reduce the temperature rise in the motor operation course.
Retaining ring is not established in the epitrochanterian sliver of the utility model end, the direct and end ring welding of sliver; Do not establish commutator; Velocity transducer is installed in the support of motor, is fixed on the right end cap, has reduced taking up room, and has dwindled motor volume.The utility model is simple in structure, and the operation temperature rise is little, and the functional reliability height is easy to maintenance.
The utility model can fully satisfy the requirement of mine alternating-current actuating system electric power wheel self-discharging vehicle to traction motor.
