How to connect two-phase motor capacitors?



There are two types of connection: forward and reverse. The first: forward connection: the main coil of 1, 2 to the secondary coil of 2, 1, so that the positive rotation.

The second: reverse connection: 1, 2 of the main coil connected to 1, 2 of the secondary coil, so that the reverse.

Connection method

Two-phase motor is also a one-way motor, one-way motor inside two sets of coils, one is the running coil (main coil), one is the starting coil (secondary coil). Start coil resistance than the resistance of the running coil is larger, the amount will know. Start the coil in series with the capacitor. That is, a series of capacitor starting coil and running coil in parallel, and then connected to the 220V voltage, which is the motor connection.

When this series of capacitor start coil and run the coil in parallel, the parallel connection of the head and tail of the two pairs of wires to determine the positive and negative rotation.

Connection method is as follows.

The first: positive rotation connection.

The main coil of 1, 2 connected to the secondary coil of 2, 1, so that the positive rotation.

The second: reverse connection.

The main coil of 1, 2 connected to the secondary coil of 1, 2, so as to reverse.
