N a measure of the magnetic strength of a magnet or current-carrying coil, expressed as the torque produced when the magnet or coil is set with its axis perpendicular to unit magnetic flux density. It is measured in ampere metres squared 电磁矩 ( symbol: mAlso called magnetic moment) → compare magnetic dipole moment
After the voltage of power source increases to 72v, the increasing rate of the electromagnetic moment of motor is very small.
当电源电压增至72 V以后，电动机的电磁转矩增大率降至很小。
When the voltage of power source changes from 0 to 100V, the electromagnetic moment of motor gradually increases, but its increasing rate decreases gradually.
电源电压从0～100V变化时，电动机的电磁转矩逐渐增大，但增大率逐渐降低。
The frequency changing start up process of generating unit actually is a synchronous driving process under the action of electromagnetic moment of the stator and rotor of motor.
机组变频起动过程，实际上是电动机依靠定子和转子的电磁力矩作用的同步驱动过程。
