Related Information
Brushless motor systems provide energy savings. Since the efficiency is higher than for an inverter-driven three-phase motor, the electricity consumption is greatly reduced. In addition, brushless motors provide a high output from a compact size. Brushless motors also provide constant torque from low speed to high speed.

Because of the different motor structure and control method, speed control range of the brushless motor is wider than that of an AC speed control motor.
Thanks to its flat torque characteristics, the brushless motor can be used over the entire speed range from low to high, even when the load fluctuates.

The specified speed is compared against the feedback signal to adjust the motor supply voltage and frequency, in order to stabilize the speed.
This mechanism ensures that the motor drives at stable speed over its entire speed range from low to high, even when the load condition fluctuates.

The compact yet powerful motor incorporates permanent magnets in the motor rotor. Compare with an AC motor having a frame size of 3.54 in. (90 mm), a brushless motor of the same specifications is 2.95 in. (75 mm) shorter and offers 1.3 times more output.
The compact motor structure lets you downsize your equipment.

Brushless motors, which incorporate permanent magnets in the rotor, generate little secondary loss from the rotor.
At an output power of 1/12 HP (60 W), for example, the power consumption of the BLF Series is approximately 23% less than that of an inverter-controlled AC motor, which enables the energy-saving operation of your equipment.
