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.

The BLE Series offer two types of AC Input drivers; RS-485 Communications Type and the Standard type. Both are easy to communicate with a PLC or host controller. 

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.

Functionality and performance can be improved by using (available for free download) the MEXE02 Support Software or the optional control module OPX-2A.

Various Settings	Speed, torque limit, acceleration time, deceleration time, I/O assignment, gear ratio, speed increasing ratio, conveyor gear ratio, conveyor speed increasing ratio, speed attainment range, overload warning level, overload warning function (enable/disable), JOG (test) run speed, JOG (test) run torque, digital/analog input signal selection Up to 16 points of operating data (speed, torque limit, acceleration time, and deceleration time) can be set*1

*¹ Specifications for the RS-485 communication type. Specifications of the standard type are up to 8 points.

*² This function is only for the control module (OPX-2A).

Speed Control Range Expanded to 80 ~ 4000 r/min

The digital speed setting function expands the speed control range to cover 80∼4000 r/min (speed ratio 50:1)

Multistep Speed-Change Operation up to 16 Speeds is Possible

Multistep speed-change operation up to 16 speeds is possible using the OPX-2A or MEXE02. Speed setting in 1 r/min units as well as separate setting of the acceleration and deceleration time are possible.

Limiting the Motor Output Torque

The motor output torque can be suppressed in accordance with the application and use condition.

Various Digital Indications are Possible (OPX-2A)

Speed, load factor, alarm code, etc. can be displayed digitally.

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.

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.

Low Cost

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

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.
