Speed Controller for Brushless DC Motors
by Design World Staff
Monday, April 30, 2007
The DEC 24/3 is a 1-quadrant amplifier range for brushless DC motors. The open board is ready-to-use with 5 to 24 V operating voltage and maximum output power of 3 A (intermittently to 6A).
It can operate as a digital and open loop speed controller because it has flexibility for use with various voltage sources (input voltage from 5 to 24 V). Operating mode is easily selected using a DIP switch. Speed value is set via an integrated potentiometer or external reference value.
The DEC 24/3 has digital signal processing. Additional setting options are available including control inputs for selecting motor direction, disable, and braking. Required maximum power is set using a potentiometer. What’s more, the unit’s end stage has under-voltage protection.
