Flat Torque CurveWide Speed Control Range and Flat Torque

The maximum motor speed of the BLV Series 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.

 


 

Slim, Yet Powerful Design

A slim body and high output are two key features of a brushless 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).

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
Electromagnetic Brake Type

The electromagnetic brake type is suitable for position holding
during standstill or gravitational operation. Note that vertical drive
(gravitational operation) requires motors of a specific power supply.

BLV-IOI/O Control System

Operation can be executed easily with I/O control.

BLV RS-485

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.

Operation Data &
Parameter Setting		 Operation Commands
(FWD, REV, etc.)
RS-485 communication, control module (OPX-2A) RS-485 communication, I/O

  • 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 potentionmeters for Speed, Acceleration/Deceleration and Torque Limiting are still active even when using either the control module (OPX-2A) or RS-485 communication.
BLV Space SavingHollow Shaft Flat Gearhead

Space-Saving and Low-Cost
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. Sine no shaft-coupling parts are needed, the parts cost and assembly man-hours will also decrease.


Higher Permissible TorqueHigh Permissible Torque
While the parallel shaft gearhead lets the permissible torque saturate at high gear ratios, the hollow shaft flat gearhead enables the motor torque to be utilized to its maximum capability.
