A Easy Way to Control High Current Load Motor Remotely

Reversing dc motor can be applied to rolling blinds / doors, projection screens, awnings. Pumps, winches, conveyors or other high power electrical appliances and equipment can be run by ac high current load motor.But how to remote control the high current load motor? Under this circumstance, we usually adopt contactor to help starting when we try to start high current load motors. A contactor is an electrically controlled switch used for switching a power circuit, similar to a relay except with higher current ratings. Contactors are heavy-duty with overload protection devices used for switching electric motors, lighting ,heating, capacitor banks , and other electrical loads.

Here take ac high power motor for example.

Firstly you need to prepare:

1 x 1 channel receiver in ac 220v (specially design for motor forward and reverse rotation)

1 x 4 buttons transmitter

2 x contactors

AC power supply

Some lines

The motor controller contains one transmitter and one receiver.

It features forward-reverse-stop capability. You can rotate the motor in forward or reversal direction by transmitter from any place within a reliable distance; wireless signal pass through walls, floors and doors.

Wiring:

Two contactors will act as a bridge between remote controller and high power motor to help activate high power motor to rotate in positive and reversal position.

Operation:

Press button ▲ on remote: Motor rotates continuously in positive direction.

Press button ■ on remote: Stop the motor.

Press button ▼ on remote: Motor rotates continuously in reversal direction.

Press button ■ on remote: Stop the motor.
