Brushless DC
+ Brake
+ Sensor

This type of motor integrates electric brake and feedback angular sensor like Hall IC or Resolver. Typical applications are for power drive unit and actuation and motion control systems. TAMAGAWA's feature is to offer such motor with electric brake, feedback sensor and control board, furthermore with gearbox and ball screws too.


  • Using rare earth magnets (Neodymium-Iron-Boron or Samarium-Cobalt type)
  • Three Hall IC for magnetic pole detection use
  • Custom designs for electrical characteristics & shape of output shaft

Brushless DC Motor + Brake

  • Robust configuration with a smaller number of parts
  • Integrated electromagnetic brake
  • High speed rotation
  • Integrated temperature sensor for stator coil

Brushless DC Motor + Gearhead

  • Robust configuration with a smaller number of parts
  • High efficiency & low backlash Planetary Gearhead
  • Combination with compact Gearhead enables high output torque
  • Custom reduction gear ratio available
