Speed Controller Overview

Overview of Speed Controllers

• These controllers vary speed of compact geared motors.

• The lineup of the speed controllers is divided into the following 4 types to meet various applications and configuration.

1. Separate type speed controller

Speed controller of the basic configuration

2. 48 mm sq. (1.89 inch sq.) speed controller

Separate speed controller housed in 48 mm sq. (1.89 inch sq.)

 

DIN size

3. Unit type speed controller

A set of a motor and speed controller: Both can be connected 

through a single-touch connector.

4. Inverter

Speed controller for 3-phase motor
