The cylindrical rotor plane brake motor is relative to the conical rotor brake motor, which is mainly composed of a spindle, a cylindrical stator, a cylindrical rotor, a front end cover, a flat electromagnetic disc brake, etc. The electromagnetic disc brake is composed of a flat disc brake disc, a flat disc friction plate, a magnetic yoke, an armature, a brake coil, a rectifier controller, etc. The friction pair is plane contact.
Characteristics of cylindrical rotor plane brake motor
The structure and size of the front end cover, mounting bolt hole division and output shaft of the cylindrical rotor plane brake motor are exactly the same as that of the conical rotor brake motor with the same power. The speed and frame number are also exactly the same as the conical rotor motor, and the two can be directly exchanged without changing the structure and parameters of the electric hoist. However, the cylindrical rotor planar brake motor also has its unique advantages:
(1) Cylindrical stator, cylindrical rotor, processing, manufacturing easy to achieve automation, assembly line production.
(2) No axial movement, intermediate shaft, coupling failure rate is low, long service life.
(3) External DC electromagnetic disc brake, easy to modular production, can achieve fast braking.
(4) Small, beautiful, no rust.
(5) Aluminum shell, good heat dissipation conditions, low temperature rise, high connection duration, can run for a long time.
(6) Energy saving. Using cylindrical motor and DC electromagnetic brake, the motor efficiency is more than 11.5% higher than the conical rotor motor with the same power.
(7) The brake action response is fast, the electric hoist brake slide is small.
(8) The motor starts and brakes smoothly, and the noise is small.
(9) High insulation level and protection level, strong environmental adaptability.
