Features of Brushless DC Motors

Brushless DC motors are more efficient and compact than AC induction motors and do not use brushes as compared to DC Brush motors. Brushless DC motors allow for quiet, long life maintenance-free operation. Brushless motors include permanent magnets in the motor’s rotor providing high power and high efficiency and built-in hall effect IC in the stator for speed detection. Speed is controlled through a driver by using feedback signals from the motor.

Wide Speed Control

Compared with conventional products, the speed control range of the brushless DC motor is greatly expanded. Use in high-speed applications even at a maximum speed of 4000 r/min is possible.

Speed Control Range

Excellent Speed Stability

The speed regulation (load) of the BLDC motor is ±0.5%.

For this reason, this mechanism ensures that the brushless DC motor drives at a stable speed over its entire speed range from low to high, even when the load condition fluctuates.

Stable Speed Control

Energy Savings

Brushless DC motors use permanent magnets in the rotor. In comparison with inverter-controlled motors, they are high-efficiency with little loss, which means that energy savings is possible.

Compact Yet Powerful

High power is achieved with a slim body, efficient gearhead and a compact design allowing for additional space savings.

Compact Brushless DC Motors

Speed Control During Vertical Operation is Possible

The electromagnetic brake type motor enables stable speed control even during vertical operation (gravitational operation).

The electromagnetic brake is automatically controlled via the driver in accordance with the operation command signal. When the power is turned OFF, such as during a blackout, the motor stops instantaneously to hold the load in place.

RS-485 Communication Type Driver

Advantages of the RS-485 Communication Type

The BLE Series FLEX RS-485 Communication Type can be controlled entirely from a host system because operation, configuration, and monitoring are fed back to the host system. When controlling with a touch-screen or panel computer, load factor and other output signals can be monitored.

  • 120 W (1/6 HP)

Hollow Shaft Flat Gear Motor

Permissible Torque without Saturation

The hollow shaft flat gearhead enables permissible torque without saturation even at high gear ratios. The motor torque can be fully utilized.

High Torque

Low Cost

By eliminating parts such as a coupling or belt-and-pulley, the parts cost and labor will also decrease.

Low Cost

Space Saving is Achieved with a Hollow Shaft Flat Gearhead

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.

Space Saving

Flexible Connection Cables

Connection / Extension Cables

Use of flexible connection cables is recommended in applications where the cable will be bent and stretched repeatedly.
