BLV Series Brushless DC Motors (BLDC Motors) (DC Input)

The BLV Series is a high power, compact brushless DC motor and driver package with 100W (1/8 HP), 200 W (1/4 HP) and 400 W (1/2 HP) motors. Driver input voltages are 24 VDC and 48 VDC respectfully and is equipped to facilitate battery power input. The driver can be controlled via I/O or RS-485 communications. By adding a parallel gearhead or the hollow shaft flat gearhead, output torques can reach 970 lb-in. An electromagnetic brake is offered for vertical or load holding applications.

Extended functions such as 8 speed ranges, torque limiting and monitoring are available with the MEXE02 software (free download) or through the use of a controller module.

Brushless DC Motors (BLDC Motors)

Optimal for Speed Control of Transportation Vehicles, Such as AGVs

  • Smooth traveling, non-meandering traveling, wide traveling speed range
  • Compact and high-torque drive motor
  • Driving continues, even if the battery volrage drops
  • Accurate stopping, and load holding when stopped

AGV Application

Can be Battery-Operated

A wide operating voltage range that can handle voltage fluctuations even if the voltage drops.

Battery Operated

Can be Driven even if the Battery Voltage Drops

The maximum motor speed of the BLV Series brushless DC motor is 4000 r/min. The speed control range has also expanded to cover velocities from 100 to 4000 r/min (speed ratio of 50:1; measured at the motor shaft), thus allowing you to program operations at various speeds from low to high.

Battery Drive

Slim, Yet Powerful Design

A slim body and high output are two key features of a brushless DC motor. The BLV Series does not disappoint users expecting these attributes. From its space-saving compact body in a frame size of 4.09 in. (104 mm), the BLV produces a high output from 1/8 HP (100 W) up to 1/2 HP (400 W).

Compact Size

Wide Speed Control Range and Excellent Speed Stability

Constant rated torque over the entire speed range is possible form low to high. Sufficient torque is acheived without the used torque being limited at low speed, like when a three-phase motor is inverter driven.

Wide Speed Control Range

No Brushes = No Maintenance

The Brushless DC Motors (BLDC Motors) do not utilize brushes, which often require replacing and/or maintenance, saving time and cost.

No brushes

Speed Stability in Feedback Control

The setting speed is compared with the speed feedback signals from the motor at all times to adjust the motor's applied voltage. A stable speed is maintained over the entire speed range from low to high, even when the load fluctuates.

Speed Stability

Speed Control Methods

Many Convenient Functions for Speed Control

Besides the basic speed control functions, there are a variety of other functions that suit a wide range of applications.

Acceleration and Deceleration Time

Acceleration and deceleration times can be set. This allows for smooth starting and stopping with little shock.

Torque Limiting

This function limits the output torque of the motor. It outputs a TLC signal when the set limiting value is reached.


Stops operation and outputs a signal
Overload/main circuit overheating/overvoltage/undervoltage, etc.


Outputs a signal at the warning level before an alarm occurs. Motor operation continues.
Main circuit overheating/undervoltage/overload, etc.

  • The test operation function is available with the control module (OPX-2A)
  • The internal potentiometers for Speed, Acceleration/Deceleration and Torque Limiting are still active even when using either the control module (OPX-2A) or RS-485 communication.

Additional Performance and Functions

Load Holding Function

The load holding function can be used to electrically hold* the load in place without an electromagnetic brake. For example, work can be performed on the load when it's held in place on a conveyor.

*It can hold a load with a rated torque of up to 50%.

Note: When the power supply to the driver is turned off, the holding torque is lost. It cannot be used to prevent falling when stopped.

Load Holding

No need for a maintenance

It is also suitable for applications where the load needs to be stopped frequently.  Since there are no mechanical parts, it contributes to a longer life. 

Load Holding

Space saving of equipment

Since no mechanical brake is required, it contributes to space saving and weight reduction in the device.

Peace of Mind for Startup and Maintenance with the Support Software MEXE02

By using the support Software MEXE02, data setting, actual operation, and confirmation via each monitor can be performed easily on a computer.

Equipment Startup Status


Operating data can be set on a computer screen. Test operatoins can be performed without connecting o the host system and the operating data is stored as-is.

Copying Data

Operating data can be copied to the driver during use on multiple units and the driver-side data read out. This contributes to reduced system startup time.

Vizualization of Various Infomration Makes "Predicitive Maintenance" Possible

What is "Predictive Maintenance"? The motor's condiition is constantly monitored and protected when signs of changes are observed in order to avoid problems.

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.
