How to use the motor housing correctly

After the motor housing heater is connected properly, the red indicator light is on. According to the size of the chassis to select the corresponding yoke (some models are equipped with two yokes), yoke without paint down, with the host core match. Then shake the yoke, the aluminum chassis through the set on the yoke, rotary yoke and host iron core fit. And then open the timer meter cover, first set the approximate time (such as 21 seconds), the knob switch to the automatic position. After the start of the heater to start the green light, the time the instrument began to read in seconds as a unit, with electromagnetic sound, the chassis is heated to reach the set time, heating equipment automatically power off. Finally remove the already heated cabinet into the tooling, the spindle vertical into the case, the spindle smoothly slide to the tooling position.

Motor (English: Electric machinery, commonly known as "motor") is based on the law of electromagnetic induction to achieve energy conversion or transmission of an electromagnetic device. In the circuit with the letter M (old standard with D) said. Its main role is to produce the drive torque, as a power source for electrical appliances or various machines. The generator is indicated by the letter G in the circuit. Its main role is the use of electrical energy into mechanical energy. On the start before the inspection method, do not know how much you know.

1, the new or long-term disabled motor, before use should check the winding and winding insulation resistance. Usually 500V below the motor with 500V insulation resistance table; 500-1000V motor with 1000V insulation resistance table; for more than 1000V motor with 2500V insulation resistance table. Insulation resistance per kilovolt operating voltage shall not be less than 1MΩ, and should be measured in the motor cooling state.

2, check the appearance of the motor without cracks, the fastening screws and parts are complete, the motor is fixed on the situation is good.

3, check the motor drive mechanism is reliable.

4, according to the nameplate shown in the data, such as voltage, power, frequency, connection, speed and power, load comparison is consistent.

5, check the motor ventilation and bearing lubrication is normal.

6, pull the motor shaft, check whether the rotor free rotation, whether the rotation when the noise.

7, check the motor brush assembly and brush mechanism is flexible, brush handle position is correct.

8, check the motor grounding device is reliable.
