COMMON ELECTRICAL DATA OF MOTORS
Common electrical data
Torque（N.m) T= Output power (kW) ÷ Rotate speed (r/min) 9550
Rated current (A) In= Output power (kW) ÷ √3 ÷ V ÷ power factor ÷ Efficiency
Synchronous speed（r/min）No= 120×Frequency Hz ÷ pole
Slip ratio (%) S= (Synchronous speed（r/min） - Rated speed（r/min）) ÷ Synchronous speed（r/min）
