Brushless DC Motors (BLDC Motors)

Wide Speed Control Range

The BLH Series adopts a unique brushless DC motor structure design to achieve a wide speed variation range. The motor of the BLH Series can be operated at varying speeds of 100 to 3000 r/min (speed ratio 30:1).

Speed Torque

Excellent Speed Stability

The driver adjusts the current flow to the motor by comparing the feedback signal of the motor speed against the set speed, in order to stabilize the motor speed. This mechanism ensures stable driving speeds from low to high, even in situations where the load condition fluctuates. With the BLH Series the speed regulation is ±0.5%.


Slim, Yet Powerful

A permanent magnet is assembled into the rotor, so the brushless DC gearmotor can produce high power from its slim body. The compact unit allows for downsizing of applications.

Compact Size

No Brushes = No Maintenance

The Brushless DC Motors (BLDC Motors) do not utilize brushes, which often require replacing and/or maintenance, saving time and cost.

No brushes

Energy Saving

The brushless DC motor has a permanent magnet assembled into the rotor, so it produces low secondary loss. The BLH Series will contribute to the energy-saving operation of your equipment.

IP65 Protection*

The brushless DC motor is protected against water intrusion should water come into contact with the motor.

The brushless DC motor must not be washed with water and is not suitable for use in an environment where it constantly comes into contact with water.

*IP40 for 15 W (1/50 HP) brushless DC motor

Compact, 24 VDC Driver

Compact Board-Type Driver

The models with an output of 1/50 HP to 1/15 HP (15 to 50 W) adopt a compact, board-type driver smaller than the size of business card. 
The 1/8 HP (100 W) driver is also compact and has dimensions of
2.80 in. [71 mm] (D) x 5.16 in. [131 mm] (W) x 1.48 in. [37.5 mm] (H)

Full Range of Driver Functions

The compact driver is packed with a full range of functions.

  • Instantaneous stop
  • Speed control via potentiometer
  • Speed control by DC voltage
  • Acceleration/deceleration time setting
  • Alarm output

Long-Life, Parallel Shaft Gearhead

  • 15 W (1/50 HP)
  • 30 W (1/25 HP)
  • 50 W (1/15 HP)
  • 100 W (1/8 HP)

Parallel Shaft Gear Motor

The high-strength gearhead is designed to withstand high-speed revolutions. The rated life of the gearhead is 10000 hours*, which is twice as long as that of our previous gearhead.

*5000 hours for gearhead equipped with 15 W (1/50 HP) brushless DC motor.

Up to 260 lb-in of Torque Possible

Hollow Shaft Flat Gearhead

  • 30 W (1/25 HP)
  • 50 W (1/15 HP)
  • 100 W (1/8 HP)

Hollow Shaft Flat Gear Motor

The output shaft can be coupled directly to your drive shaft without using a coupling. The flexible installation modes, such as installation on either the front or rear face or by using the center shaft, allows you to reduce the size and installation space of your equipment. Since no shaft-coupling parts are needed, the parts cost and assembly man-hours will also decrease.

Up to 600 lb-in of Torque Possible
