BLV Series Brushless DC Motors (DC Input)

BLV Series Brushless DC Motor Speed Control Systems

BLV Series Brushless DC Motors (DC Input)

The BLV Series is a high power, compact brushless DC motor and driver package with 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 through the use of a controller module.

  • 24 or 48 VDC
  • Network Communications (I/O or RS-485)
  • Parallel Shaft, Hollow Shaft Flat Gear or Round Shaft (no Gear)

Brushless DC Motors

Wide Speed Control Range and Flat Torque

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.

Wide Speed Range

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 1/4 HP (200 W) up to 1/2 HP (400 W).


No Brushes = No Maintenance

The brushless DC motors do not utilize brushes, which often require replacing and/or maintenance, saving time and cost.

No brushes

Energy Savings

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

Equipped with Functions to Facilitate Battery Drive

  • Capable of driving even if the battery voltage is low
  • A warning output notifies when the battery voltage is low

RS-485 Communication System

RS-485 communication lets you set operating data and parameters and enter operation commands. A single programmable controller connects up to 31 drivers and provides multi-axis synchronous starting.

The protocol of the RS-485 communication system supports Modbus RTU, allowing it to easily connect with programmable controllers, touch panels and other devices.

  • FWD input, REV input and other operation commands can also be controlled from I/O.
  • 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.

Extended Functions with Control Module (sold separately)

Control Module OPX-2A

Functions can be extended and settings shown on a digital display by using a separately sold control module (OPX-2A). It can also be used in RS-485 communication mode.

Long-Life, Parallel Shaft Gearhead

  • 200 W (1/4 HP)
  • 400 W (1/2 HP)

Parallel Shaft Gear Motor

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.

Up to 610 lb-in of Torque Possible

Hollow Shaft Flat Gearhead

  • 200 W (1/4 HP)
  • 400 W (1/2 HP)

Hollow Shaft Flat Gear Motor

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 Motor

Electromagnetic Brake Models Available for Vertical Drive

The motor with an electromagnetic brake enables stable speed control even during vertical drive (gravitational operation). When the power is turned off, the motor stops instantaneously to hold the load in place. The electromagnetic brake is automatically controlled via the driver in accordance with ON/OFF of the operation command signal.
