We have Coreless motors of Dia4-Dia22.
Please select in accordance with your design.


Main features of Coreless motor

  • Ultra compact design (Small size and light weght)
  • Energy saving(Low electrcity consumption)
  • Excellent controllabilty
    (Low mechanical time constant and quick response)
  • High efficiency(No iron core plus hight effciency)
  • Smooth motive power
    (constant rotation without cogging.)
  • Low electrical noise(Long life)

Brushless motor Guide


The standard is coreless brushless motors and the basic policy is to develop in accordance with customer's request.
We are pleased to support the customer from the development phase.

Main features of our brushless moters

  • Less electrical noise, Less mechanical noise
  • Long life
  • Low vibrations
  • Running at high speed is available

Gear head Series Guide


We have gear head series of Dia12-Dia16
Please select sutable gear head model calculating
by following formula.

Basic formula of gear head selection

1. Calculation of speed
i : Reduction Ratio
ηTransfer effciency
(η1: First reduction )
(η2: Second reduction)
2. Calculation of torque
Tout=Tin x i x η
Nout : Output speed
Nin : Input speed
Tout : Output torque
3. Calculation of a transfer effciency

(*Please calculation ηη as 0.9)
Tin : Input torque
