| Series ACelectromagnetic brake three phase asynchronous motor | |||
| 产品概述 | |||
| 英语 | The YEJ3 series electromagnetic brake motor is an improved product of the YEJ series, complying with the national standard JBT6456-2010, and its electrical performance meets the technical standards of the YE2 series motors. This series of brake motors is equipped with an electromagnetic brake at the non-drive end of the motor. When the motor loses power, the brake disc of the electromagnetic brake automatically presses against the motor's rear cover, generating frictional braking torque to stop the motor. The no-load braking time varies with the frame size, ranging from 0.15 to 0.45 seconds. The power supply of the brake must be linked to the motor, with synchronized operation. The YEJ3 series motors are widely used in mechanical processing machine tools, conveyor machinery, as well as in machinery for packaging, woodworking, food, chemical, textile, construction, shops, roller shutters, and other drives. | ||
