3.3 Motor reverser
A motor inverter is a component that is connected upstream of a single-phase motor. It reverses the direction of rotation of a single-phase motor. Its operation is simple, it starts or stops the single-phase motor and can also change the direction of rotation. The change in direction of rotation is achieved by changing the coupling of the capacitors of the single-phase motor.
To change the direction of rotation of a single-phase motor, it is normally necessary to change the direction of the coupling strips in the motor terminal box. Tools and pliers are used to make this change. With the motor inverter you can do this easily. The inverter is placed upstream of the single-phase motor and makes the change automatically.
There are 2 types of motor inverters:
- A type 2 manual motor inverter:
This inverter is fully assembled. It consists of an electrical box, a 230V single-phase supply voltage with a power rating of 3kW, and two cable glands for the supply and output of your motor. On the box you will find a 3 position button: 1, 0, or 2
-A type 1 motor inverter to wire:
This inverter is to be mounted and wired. It exists in 2 models depending on your control voltage: 24 AC/24 VAC or 230 AC/230VAC. It is fixed on a DIN rail and is mounted on an electrical cabinet. The motor supply voltage must be 230V single phase with a control voltage of 230 VAC or 24VAC. The maximum permissible power is 50 kW. Unlike the type 1 motor inverter, the direction of rotation reversal button is not provided.
