Abstract

The invention relates to a conical rotor DC permanent magnet braking motor, which includes a casing, a main shaft, a stator core, a rotor core and a brake. Swimmingly supported on the left and right end covers, a spring thrust device is provided between the rotor core and the left end cover, the brake is a friction brake, including matching dynamic brake parts and customized brake parts, and the dynamic brake parts are fixed on the left end. On the main shaft outside the cover, the custom stopper is fixedly connected with the left end cover, the main shaft speed is 200r / min-900r / min, and the braking torque is 50N / m-2000N / m. The invention enables the DC permanent magnet motor to have a braking function, and when it is used in occasions such as driving a crane reel, the structure of the whole machine can be significantly simplified, the overall volume can be reduced, and the manufacturing cost and operating cost can be reduced.

Description

technical field [0001] The invention relates to a conical rotor DC permanent magnet braking motor. Background technique [0002] The rotor and stator of the existing DC permanent magnet motor are both cylindrical / cylindrical. When energized, the magnetic field of the stator generates a circumferential force on the rotor, which pushes the rotor to rotate, and then drives other equipment to run through the output shaft of the motor. Magnetic motors are small in size, large in output, low in noise, wide in speed regulation range, easy to control, and can be used in several occasions. However, in occasions such as a crane hoisting mechanism, it is required that the actuator should run when the motor is energized. An independent brake is set somewhere, and the brake is powered on and off synchronously with the motor. In the power-off state, the brake is in the braking state, relying on the braking force generated by the spring, etc., and forms a brake under the braking force bet...
