Easy Connection, Easy Operation

The motor can be connected simply by plugging the connector into the driver. There is no need for troublesome wiring. The motor speed can be set using the potentiometer on the front panel easily.

External Control Possible

Start/stop, rotation direction switching and instantaneous stop can be controlled using external signals. You can also switch between sink logic and source logic in accordance with the output type of your controller.

Speed - TorqueWide Speed Control Range

In addition to feedback control, the BLU Series adopts a unique motor structure design to achieve a wide speed variation range. The motor of the BLU Series can be operated at varying speeds of 100 to 2000 r/min (speed ratio 20:1).


 

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 BLU Series the speed regulation is ±0.5%.

Compact SizeSlim, Yet Powerful

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


 

Power Loss ComparisonEnergy Saving

The brushless motor has a permanent magnet assembled into the rotor, so it produces low secondary loss. At an output of 90 W (1/8 HP), for example, the BLU Series is approximately 50% less than the power consumption of an inverter-controlled AC motor. The BLU Series will contribute to the energy-saving operation of your factory automation equipment.


IP65 Motor Structure

The motor is protected against water intrusion, should water come in contact with the motor. The motor must not be washed with water and is not suitable for use in an environment where it constantly comes in contact with water.

Parallel Shaft GearheadLong-Life Parallel Shaft Gearhead

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.
