T=7.5*9550/960=74.6Nm for 7.5kw
T=11*9550/1450=72.4Nm for 11Kw
As in the above comparison, the torque of the 7.5KW is greater.
An electric motor (Motor) is a device that converts electrical energy into mechanical energy. It is the use of energized coils (also known as stator windings) to produce a rotating magnetic field and act on the rotor (such as squirrel cage closed aluminum frame) to form a magneto-electric power rotating torque. Motor according to the use of different power sources are divided into DC motors and AC motors, most of the electric motors in the power system are AC motors, which can be synchronous motors or asynchronous motors (motor stator magnetic field speed and rotor rotational speed does not maintain synchronous speed). Motor mainly consists of a stator and rotor, the direction of the energized wire in the magnetic field force movement is related to the direction of the current and the direction of magnetic inductance (magnetic field direction). The working principle of the motor is the role of the magnetic field on the current force, so that the motor rotation.
