3 phase asynchronous motor

asynchronous motor, 3 phase asynchronous motor, general induction motor: YD series multi-speed motors were designed based on Y series motors, this type of motors have a single winding, but through change its connection, the motor changed to different poles, thus it runs under different speed and with different output power. YD series multi-speed motors owns all the advantages that Y series motors have, they are widely used in the mechanism which needs stepped-speed adjustment, such as compressors, machining equipments, transportation system, agricultural mechanism, food processing mechanism etc. We also supply special designed multi-speed motors according to customers unique requirements. Available type Including double-speed motors and multi-speed motors. Available from frame 80 to frame 280, frame 315 on request Rated output: 0.37KW 200KW B3 /B5 /B14 /B35 /B34 mounting Mounting dimensions according to IEC60034 standard Operating Conditions Ambient temperature: -15 40 Altitude: up to 1000 meters Rated voltage: 380V, 400V, 415V Rated frequency: 50Hz or 60Hz Connection: Star-connection for motors 3KW and lower output power Delta-connection for motors 4KW and up output power Duty: S1 (continuous) Protection: IP44 Insulation class: B Cooling method: IC411
