MOTOR STARTER SOLUTION

READ MORE

Inoréa, industrial supplier of automation and electrical components, offers a range of products for starting your three-phase or single-phase motors. You can change the direction of rotation of your motor, remove inrush currents and start your electric motors. We offer you : - Soft starters for electric motors. - Star-delta starter boxes. - Electric motor inverter boxes - Electric motor starter boxes

What is a soft starter?
A soft starter allows the inrush current to be eliminated when starting an asynchronous electric motor. It thus carries out the starting phase gently, by applying a voltage ramp to the windings of the electric motor.

What is a star-delta starter box?
The star-delta system allows for a two-stage start of asynchronous electric motors. The delta coupling is first used to supply the windings with undervoltage, thus limiting the current draw. A time delay then switches the coupling to star and allows normal operation of the electric motor. A star-delta start cannot be used on a 220/400 motor unless the mains voltage is 220V three-phase. To use a star-delta start on a 400V three-phase electrical network, the motor must be 400/690V. The current is divided by 2 under the main contactor, this must be taken into account when sizing the thermal relay. This is not the case if the motors are protected upstream of the main contactor with a motor circuit breaker.

What is a motor inverter?
A motor inverter is used to change the direction of rotation of a single-phase or three-phase motor. It is connected upstream of the motor to switch it on or off. This makes it easy to change the direction by reversing 2 phases on the three-phase electric motor. On single-phase motors, the reversing boxes take into account the starting capacitors and permanent capacitors for reversing the direction of rotation.

What is an electric motor starter box?

A motor starter box is used to start electric motors and also to reverse the direction of the motor. They are used on three-phase electric currents. Equipped with thermal relays, they are protected against overloads and the loss of a phase.
