Description

technical field

[0001] The invention belongs to the technical field of DC motors, in particular to a DC motor with double excitation windings. Background technique

[0002] The motor generates motion force through the interaction of magnetic force. The motor mainly includes a stator and a rotor. The stator is the static part of the motor. The stator is composed of three parts: stator core, stator winding and frame. The main function of the stator is to generate a rotating magnetic field, while the main function of the rotor is to be cut by the magnetic force lines in the rotating magnetic field to generate current. Usually, when the motor is running under load, it is powered by an external power grid. When the load drops, the potential energy will drag the motor to run, causing energy to be consumed by resistance heating, resulting in energy waste.

[0003] At present, the energy recovery of crane load potential energy includes energy-saving technology and related products...
