SHSD24-01A 7.5~ 26.4 All models of NAMIKI brushless motors

Brushless motor driver SSD06-R5A

Used for brushless motor drive control.

SSD06-R5A is a 3-phase sensorless-dedicated driver that can be used to drive our BMN04-08XX and BMN07-12XX motors. The FG pulse outputs a square wave of 1 pulse per rotation. The direction of rotation (CW/CCW) differs depending on the motor.

Brushless motor driver SHSD24-01A

Used for brushless motor speed control.

SHSD24-01A is a drive controller for NAMIKI brushless motors, supporting motors with built-in hall sensors as well as sensorless models. It immediately readjusts the supply voltage when there is a deviation between the actual rotation speed and the command value. Safeguards include restraint protection, overcurrent protection, and current limiting functions, and the status can be verified by LED, LCD*, and analog voltage output.

Drive mode

EXT/IO Rotation speed and direction can be controlled using external input/output signals.
VR Rotation speed and direction can be controlled using the built-in potentiometer and switch.
PC Rotation speed and direction can be controlled by PC using RS232C communication. Dedicated software is required.
