excavator OEM pilot oil filter
Hangzhou Dingteng Industrial Co.,Ltd | Updated: Oct 11, 2017The excitation windings of his excitation DC motor are connected to the independent excitation power supply, and the excitation current is also more constant, and the starting torque is proportional to the armature current. The speed change is also 5%~15%. It is possible to reduce the rotational speed by weakening the constant power of the magnetic field or by reducing the voltage of the rotor windings. The stator magnetic poles of the compound excitation DC motor have the same excitation windings, and the series excitation windings connected with the rotor windings (fewer turns) are arranged.
