IC611 3 Phase Squirrel Cage Asynchronous Motor IP54 IP55

Y710 Squirrel Cage High Voltage Electric Motors Rolling Bearing Ip54 Ip55 Ic611

Y and YR are the basic series, the protection grade is IP23, and the cooling method is IC01. On this basis, various motors with different protection grades and cooling methods can be derived, such as YKS (air-water cooling), YQF (climate protection), YKK (air-air cooling), YRKS, YRQF, YRKK and other series motors.

The rotor of the asynchronous motor adopts advanced computing technology to calculate the starting temperature rise and stress of the squirrel-cage rotor, so as to prevent the motor from early damage due to excessive starting load. Users are advised to check:
(1) The moment of inertia of the rotating part of the driven mechanical equipment (converted to the motor speed) should not exceed the value in the item (load J) in the technical data sheet;
(2) The user's power grid should ensure that the motor terminal voltage of the motor during the starting process is not lower than 85% of the rated voltage;
(3) The resistance torque characteristics of the driven machinery are the resistance torque characteristics of pumps and fans.
Under the above conditions, the motor is allowed to start twice continuously in the actual cold state, and the motor stops naturally between the two starts; or starts once in the hot state of the motor. Restarting the motor beyond the above limit should be done after stopping for 1 hour.
If the moment of inertia of the mechanical rotating part of the motor drive is required to exceed the (load J) value in the technical data sheet, or the motor is required to be started frequently, or the motor may be started with a heavy load, be sure to contact our company in advance to negotiate, so that special Designed to ensure reliable starting of the motor.
