GB/T 22711-2008 Specification for high efficiency three-phase permanent magnet synchronous motor(frame size 132~280)
Basic Information
Scope
This standard specifies the types, basic parameters and dimensions, technical requirements, inspection rules, and requirements for packaging, marking, and warranty period of self-starting high-efficiency three-phase permanent magnet synchronous motors.
This standard applies to self-starting high-efficiency three-phase permanent magnet synchronous motors (frame number 132~280) (hereinafter referred to as motors). The high-efficiency three-phase permanent magnet synchronous motors specified in this standard are suitable for oilfield beam pumping units and similar high starting torque loads, with a pole number of 6 and 8. The rotor is equipped with a cage-type starting winding. This standard does not include AC servo permanent magnet synchronous motors.
