Note: behind the governor in the middle of the 2 connectors there is an AC logo is connected to the power supply. Single-phase 220V, governor and motor directly connected, pay attention to the direction, do not insert the reverse, the color of the line should be corresponding. Turn on the power, the motor can turn, governor control speed.
If the direction is reversed, change the connection line behind the governor, there are tips, that is, the two power connectors above, there are CW, CCW tips. The three wires from the motor, the 2 wires from the governor, and one is the ground wire, which is directly connected to the governor connector.
Wiring diagram is as follows:
Single-phase motors are not only in the production of a large amount, but also with people's daily lives, closely related, especially with the growing standard of living of the people, the use of single-phase motors for household appliances and equipment, but also more and more.
Applied in the production of micro-pumps, grinders, threshing machines, pulverizers, woodworking machinery, medical equipment, etc., in terms of life, there are fans, hair dryers, exhaust fans, washing machines, refrigerators, etc., a wider variety of types, but the power is smaller.
Extended informationSingle-phase motor starting principle: when the single-phase sinusoidal current through the stator winding, the motor will produce an alternating magnetic field, the strength and direction of this magnetic field at any time for the sinusoidal law changes, but in the spatial orientation is fixed, so it is also known as the magnetic field is alternating pulsating magnetic field. The alternating pulsating magnetic field can be decomposed into two rotating magnetic fields with the same rotational speed and opposite rotational direction.
When the motor with an external force to a certain direction of rotation (such as clockwise rotation), then the rotor and clockwise rotation direction of the rotating magnetic field between the cutting line of magnetic force movement becomes smaller, the rotor and counterclockwise rotation direction of the rotating magnetic field between the cutting line of magnetic force movement becomes larger. Thus the equilibrium is broken, and the total electromagnetic torque produced by the rotor will no longer be zero, and the rotor will rotate in the direction of propulsion.
Forward and reverse principle of single-phase motor, single-phase motor inside two sets of coils, one is the running coil (main coil), a group of starting coil (sub-coil), most of the motor's starter coil is not just start up after the unused, but has been working in the circuit. The start coil resistance is larger than the running coil resistance, the start coil is strung with a capacitor, that is, the start coil is strung with a capacitor and the running coil is connected in parallel.
