  • Motors are designed small and high performance
  • We recently released a special magnetic circuit design motor. This motor design is smaller and has a higher performance than conventional FED, FYD series motors.
  • Wide range (200 r/min-2500 r/min 60 W:65 r/min-2500 r/min), stepless speed control.
  • Very steady characteristics (Feed back control employed).
  • Speed pulse output can be used for speed monitoring, simplified position control...
  • Direction of rotation can be monitored by this signal.
  • At an over-load condition, the motor stops and an alarm signal is output.

Protection Functions

N/A Over load protection
When an exceeding torque than rated is applied to motor for more than about 5 sec., Stop motor and outputs "L" from "ALARM" (20W, 40W) or "ALARM OUT" (60W).
To release alarm :
Palm Mini PLUS type: Disconnect power supply for more than 1min
J-Book type: Input "L" to "ALARM RST" for more than 1sec. Do not measure/judge by this operation whether the motor is overloaded or not.
