The YEJ metalworking lathes ac electrical motor is a fully enclosed self-fan-cooled squirrel-cage three-phase asynchronous motor with an additional disc type DC brake. It has the advantages of rapid braking, simple structure, high reliability, and strong versatility. In addition, the brake has a manual release mechanism and is widely used in various mechanical equipment and transmission devices that require quick stop and precise positioning.The flange installation dimensions of this series are the same as the Y2 series.

What are some common power?
The recommended values
for the power grades of small and medium-sized motors determined in our national standards are as follows (KW): 0.18, 0.25, 0.37, 0.55, 0.75, 1.1, 1.5, 2.2, 3, 4, 5.5, 7.5, 11, 15, 18.5, 22, 30 , 37, 45, 55, 75, 90, 110, 132, 160, 200, 250, 315, 355, 400, 450, 500, 560, 600, 630, 710, 800, 850, 900, 950, 1000, 1120 , 1250, 1400, 1500, 1600, 2000, 2240, 2500.
The rated voltage UN of a three-phase motor is the voltage that guarantees the normal operation of the motor, generally refers to the line voltage, and uses volts (V) or kilovolts (KV) as the unit. Low-voltage motors in my country are generally 220V or 380V (the former is less used); high-voltage motors are 3KV, 6KV and 10KV. The actual power supply voltage used by the motor should generally be between 95% and 105% of the rated value, and it can be relaxed to 90% to 110% when required. When two voltages are available, separate them with a "/" line, such as 220/380V.
