YD multi-speed three phase electric motor is one of the main series products deriving from three-phase series. The motor can change rotational speed to meet the requirements of load state, so that they can properly match the demands of power and simplify adjustments speed system. They are widely used in such industrial and agricultural departments, as machine tools, mining metallurgy, spinning and weaving, printing and dyeing, chemical industry and agricultural machine. YD motor is equivalent to other foreign advanced machines, and therefore they are matching with single-machine or machine for export as well as motors for similar types imported from abroad.

FAQ
What causes the oil pump motor to catch fire? How to prevent it?
1. Frequent startup
Each time the motor is started, it has to withstａnd the impact of the locked-rotor current. If it is started several times in a short period of time, the winding will burn due to the sharp increase in temperature.
2. Poor contact
When the internal and external wiring of the motor is loose, resulting in poor contact, the contact resistance increases, causing the joint to overheat, or even "fire" and discharge, causing winding insulation and burning of combustible objects around it.
3. Short circuit of iron core
Due to poor quality or manufacturing process, the iron core of the motor is short-circuited, and the eddy current loss increases significantly, which causes the iron core to overheat, which causes the motor to catch fire.
4. Mechanically locked rotor
When the motor is improperly installed or foreign matter enters, the rotor is jammed due to insufficient lubricating oil or dirty lubricating oil, or the driven machinery is jammed, causing the current of the motor to increase sharply, causing the winding temperature to rise too high And on fire.
