Heavy Duty Lifter with Brushless DC Motor and Flat Hollow Shaft Gearhead

Issue: Need to lift something heavy in a tight space, but an AC gear motor with electromagnetic brake is too large to fit.

While AC gear motors are available as an alternative to brushless DC motors, they can take up more space especially with an electromagnetic brake or an external brake system.

Challenge:

AC gear motors are already bulky; especially with a high gear ratio. An electromagnetic brake increases the motor length even more.
If a built-in electromagnetic brake isn’t offered on the motor, an external brake system needs to be integrated.

Solution: BLE2 Series Electromagnetic Brake Type Hollow Shaft Gear Motor and Driver

Brushless DC Motor and Flat Hollow Shaft Gearhead and Driver

Save space with a compact and efficient brushless DC motor with an integrated electromagnetic brake that automatically engages to hold the load in place. The rotary motion from the motor can be converted to linear motion by adding a linear actuator. Brushless DC motors can be an alternative for linear motion applications that don't require the precision of servo motors or stepper motors.

Compact, Integrated Gear Motor with an Electromagnetic Brake

By combining a compact BLDC motor body, a high torque hollow shaft flat gearhead, and a built-in electromagnetic brake, the BLE2 Series electromagnetic brake type hollow shaft gear motor is an integrated compact solution that can help save space while maintaining high load capacity with safety in mind.

Hollow Shaft Flat Gearhead Increases Max Torque and Saves Space

Compared to parallel shaft gearheads, a hollow shaft gearhead saves space by decreasing the overall length and removing the coupling. The permissible torque of a hollow shaft flat gearhead is also higher than a parallel shaft gearhead in the high gear ratios.

Built-in Power-Off Activated Electromagnetic Brake

Ideal for applications with vertical loads, a built-in electromagnetic brake automatically engages when power is removed, providing sufficient holding force to hold the load safely in place in the event of a power failure.

Advanced Driver Functions Enable Flexibility

The driver is equipped with four methods of data setting and various functions that correspond with your purpose of use. By using data setting software, equipment start-up and checking operating status is simple. Functions are provided in accordance with the customer's usage conditions.
