new series YEJ motor are full-closed, fan-cooling
squirrel-cage three phase asynchronous ones with disc D.C
electromagnetic brakes, nation-widely unified and designed.
The series YEJ motor have advantages of high efficiency, high
starting torque, quick braking, less vibration, low noise.
According with IEC standard, their mounting sizes are as same
as the series "y". In addition, the brake has a hand
reliving device, which makes it not only have function of hand
reliving, but also have function of electro tripping.
The series YEJ motor are suitable for main shaft
transmissions and auxiliary transmissions which are required
quickly to stop, exactly to position, reciprocatedly to
rotate, transport, package, food, print, construction,
textile, woodworking, retarding, metallurgical and forging
The D.C disc brake of the series YEJ motor is mounted on
shaft-extending end. Turn on the motor, the brake will operate
at the same tine. By the action of electromagnetic attraction,
the electromagnetic will attract the armature, the spring will
be compressed to make the braking disc separate from the
armature and cover, and the motor starts to rotate. And turn
off the motor, the electromagnet of the brake will lose
attraction, the spring will push the armature to make it press
the braking disc tightly, and the motor will stop working
immediately by the action of the friction force moment.
The rated voltage and frequency of the series YEJ motor are
respectively 380V, 50Hz. A rectifier within the wiring box
supplies power for the brake.
Surrounding Temperature: not higher than 40.
Altitude: not higher than the sea level elevation of
Humidity: not higher than 95¡§G.
Rate Voltage: 380V. Rate Frequency: 50 Hz.
Connection: " Y "type for 3 KW and
downwards, and "D"type for 4 KW and upwards.
Operation Mode: continuing(S1).
