How to judge whether the power line of horizontal vibration motor is reversed

Many users connect the head and tail of horizontal vibration motor reversely when using it, which will affect the normal use of horizontal vibration motor. Today, I will teach you three ways to check whether the horizontal vibration motor is connected in reverse.
 Horizontal vibration motor
There are three methods to check whether the horizontal vibration motor is connected reversely: needle inspection method, bulb inspection method and multimeter inspection method.
1. Needle inspection method: in the winding of a horizontal vibration motor, sometimes the relationship between one phase and the other two phases is wrong due to the wrong initial wire ends of one phase, or when the △ or Y connection method is connected, so the whole phase is connected in reverse. If the winding is △ connected, the contact points of any two phases of the triangle are disconnected, and DC is applied to the winding of the horizontal vibration motor in series. Then a magnetic needle is installed in the inner circle of the stator core, and the magnetic needle is slowly moved along the inner circle of the stator core to check the polarity of each coil group. If the winding wiring of horizontal vibration motor is correct. When the magnetic needle moves around the inner circle of the stator core, the number of times that the magnetic needle changes direction should be 3 times of the number of winding poles of the horizontal vibration motor.
2. Bulb inspection method: firstly, it is necessary to distinguish which two wire ends belong to the same phase horizontal vibration motor winding, determine their start end and end, connect any two-phase horizontal vibration motor winding in series, connect the bulb, and connect the third phase horizontal vibration motor winding to 36V low-voltage AC. If the bulb is on, it means that the two-phase horizontal vibration motor winding head and tail are connected reversely. If the connection is reversed, the coupling joint should be re tried.

3. The multimeter inspection method is to rotate the rotor of horizontal vibration motor when testing with multimeter. If the pointer of the multimeter does not move, it indicates that the connection of the winding head and tail of the horizontal vibration motor is correct. If the pointer of the multimeter rotates, it indicates that the connection of the winding head and tail of the horizontal vibration motor is wrong, and the coupling joint should be tried again.
