BLH Series Brushless DC Motors (DC Input)
BLH Series Brushless DC Motors (BLDC Motors) - DC Input
The BLH Series Driver has been updated to now include three driver types; RS-485 Communications type, a Digital type driver or the traditional Analog type. The BLH Series is a 24 VDC, brushless DC motor and driver package offering a wide speed range of 100 to 3000 r/min (80 to 3000 r/min with digital driver type). RS-485 Communication and Digital type driver is used with our MEXE02 support software (available for free download) for improved functions including torque sensing and predictive maintenance monitoring. A wide range of motor options are available to meet you application needs.
The BLH Series comes with long-life, high-strength gearheads that can produce up to 600 lb-in of torque.

Brushless DC Motors (BLDC Motors)
Brushless DC motors have slim bodies and provide high output and high efficiency due to the built-in permanent magnets. The built-in sensor (hall IC) constantly monitors the motor's speed. No matter the load conditions, feedback control is carried out at all times so that the command speed and actual speed remain constant.
Speed stability with feedback control
Brushless DC motors compare the setting speed with the speed feedback signals from the motor at all times and adjust the motor's applied voltage. Speed is kept stable over the entire speed range from low to high even when the load fluctuates.
IE4-equivalent* high-efficiency and energy-saving motor
Brushless DC motors are higher efficiency than three-phase motors (induction motors).
Broad speed control range and flat torque
Rated torque is consistent over the entire speed range from low to high. Sufficient torque is obtained without limiting the used torque at low speeds, as is done with three-phase motors when driven with an inverter.
Compact, lightweight and high power
Since these are brushless DC motors with built-in permanent magnets, they offer high output even though they are compact. Installation is easy and both equipment weight and space can be reduced.
3 Types of Drivers to Choose From
Analog Setting Type
- Installation and functional compatibility with current products
- Increased Performance (higher torque, reduced audible noise)
- 15 W, 30 W, 50 W and 100 W
RS-485 Communications Type
- Installation compatibility with current products
- Increased Performance (higher torque, reduced audible noise)
- Increased functionality with Support Software (MEXE02)
- 15 W, 30 W and 50 W
Digital Setting Type
- Installation compatibility with current products
- Increased Performance (higher torque, reduced audible noise)
- Increased functionality with Support Software (MEXE02)
- 15 W, 30 W and 50 W
Compact Board-Type Driver
Compact, lightweight drivers that are smaller than a business card.
Full Range of Driver Functions
The compact driver is packed with a full range of functions.
- Instantaneous stop
- Speed control via potentiometer
- Speed control by DC voltage
- Speed control by MEXE02 support software (RS-485 or Digital type)
- Acceleration/deceleration time setting
- Torque Limiting Function (RS-485 or Digital type)
- Alarm output
Increase Performance and Value with New Drivers
Reduction in Equipment Tact Time
Suitable for Applications in Quiet Environments
Noise Value approx. 44 dB (reduced by approx. 13 dB)
Noise sounds about half as loud as conventional products.
*30W with parallel shaft gearhead (5:1)
*Measurement of noise: OA value
The BLH Series uses a sinusoidal drive method. With little torque ripple and smooth, stable rotation even at low speeds, the motor's drive sound is reduced.
Synchronized Operation and Operation with Little Speed Fluctuation
Startup and Maintenance with Digital Settings + Support Software
Equipment Startup Assistance
Operating data can be set on the computer screen. It is possible to perform a test run without connecting the host system, then record the operating data as-is.
Copy the operating data to the driver when using multiple units and read out the data on the driver side. This contributes to reduced system startup time.
Predictive Maintenance with Visualization
What is predictive maintenance? By constantly monitoring the status of the motor and performing maintenance when signs of change are observed, trouble can be avoided.
Torque Adjustment
Besides applications such as adjustment of tightening force, it can also be used as a safety measure for pinching detection and equipment damage prevention. he max. instantaneous torque range can be set between 0 and 200% by assuming the rated torque to be 100%.
Operating Data Setting
When using the digital setting type, operating data for up to 8 points can be set.

*5000 hours for gearhead equipped with 15 W (1/50 HP) brushless DC motor.
Up to 260 lb-in of Torque Possible
[100 W (1/8 HP) Brushless DC Motor with Parallel Shaft Gearhead]
Hollow Shaft Flat Gearhead
- 30 W (1/25 HP)
- 50 W (1/15 HP)
- 100 W (1/8 HP)
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.
Electromagnetic Brake
- 30 W (1/25 HP)
- 50 W (1/15 HP)
- 100 W (1/8 HP)
Stop and Hold Using Electromagnetic Brake
- The stop position can be maintained when stopping the equipment to load and unlock or process work pieces.
- Hold loads during unexpected occurrences such as power outages.
Confirm motor is stopped by MOVE output
- The electromagnetic brake release timing can be confirmed using the MOVE output for digital setting type and RS-485 communication.
Driver Cable Set*
Power supply cable is used to connect the driver and the power supply. I/O signal cable is used to connect the driver and programmable controller.
