Second, the disadvantage of high-voltage motor is large inertia and difficult starting and braking.
3. High-voltage motors can be used in mines and petrochemical enterprises.
Fourth, high-voltage motors can be divided into high-voltage synchronous types; High voltage asynchronous type; High voltage asynchronous winding type; High-pressure squirrel cage and so on.
Five, the working principle of high voltage motor
1, input motor power.
2. Current generates electromagnetic induction between stator and rotor.
3. Adopt the principle of electromagnetic repulsion.
4. Push the rotor
5. Rotating to do work produces force.
6. The force generated by rotation drives other equipment.
6. What are the maintenance procedures for high-voltage motors?
1, winding, according to the voltage level of the motor,
2. Bandage before molding. The purpose of wrapping is to protect the outer insulation, interlayer insulation and turn-to-turn insulation of the coil from being damaged.
3. Forming, which is completed by a molding machine.
4, plastic, in order to prevent the embedded line can't squeeze down, causing embedded line difficulties.
5. Bind mica tape and hot press. The purpose of hot pressing is:
(1), which is convenient for line embedding after setting.
(2) It can be moisture-proof and waterproof.
(3), prevent corona discharge to the slot.
(4), complete the closed to the outside world, to avoid high voltage breakdown.
6. Test the withstand voltage,
7, embedded wires, all embedded wires are connected, and the whole motor is pressed again.
8. Dip paint, the purpose is to solidify the insulation between the bar and the wires inside and outside the slot, and prevent vibration from damaging the insulation structure.
9. Test, using the whole machine parameter test.
