YD variable-pole multi-speed induction 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
How to prevent motor fire?
1. In order to meet the requirements of moisture-proof, anti-corrosion, dust-proof and explosion-proof, choose the appropriate motor according to the different working environment.
2. The motor and its starting device should keep a proper distance from combustible objects. No debris should be piled around the motor.
3. Each motor should be equipped with an independent operating switch and suitable protection devices.
4. In order to prevent mechanical damage, the cable should be connected to the motor with a protective tube, and the lead-in cable joint or cable sleeve should be directly connected to the motor junction box.
5. For motors that have not been used for a long time, the insulation resistance of their windings should be measured before use, and the insulation resistance value should be greater than 0.5MΩ.
6. The daily inspection and maintenance work should be done for the running motor, and the problems should be dealt with in time. The power supply voltage should be checked frequently, the fluctuation should be less than +10% or -5%, the voltage unbalance should be less than ±5%, the current unbalance should be less than 10%, and the temperature rise should not exceed the specified value.
When a fire occurs in the motor, the power supply should be cut off immediately. For rotating electric motors, the shaft and bearing should be prevented from deforming during fire fighting. Do not use dry powder, sand, soil and water when extinguishing fires. Only carbon dioxide, carbon tetrachloride, 1211 fire extinguishers and steam, etc. can be used to prevent impurities, hard objects and water from falling into the motor, damaging the insulation and bearings, and causing more consequences. serious
