VEXTA Step Motors
BLV Series Brushless Speed Control System
BLV Series

The BLV Series are compact, DC input brushless motors and drivers with output options of 200 W or 400 W. An extensive variety of motors lets you select the model that best suits your specific application. Available in both standard and electromagnetic brake type.

Flat Torque Curve

 

 

 

 

Wide 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).

Hollow Shaft Flat Geared
  • Basic model of motor
  • 100 ~ 4000 r/min speed range
  • Dedicated high-strength gearhead
  • Rated for up to 10,000 hours
  • Hollow shaft for direct coupling
  • Higher strength and permissible torque than standard parallel shaft gearheads

Hollow Shaft Flat Gearhead Type

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. Since no shaft-coupling parts are needed, the part's cost and assembly man-hours will also decrease.

High 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.

Space Saving

The output shaft can be coupled directly to a driven shaft without
using a coupling, which allows you to reduce the size and installation
space of your equipment.BLV Space Saving

Additional Features Available


Comes in an 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.

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

Extended Function


OPX-2A

Control Module OPX-2A (sold separately)

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.

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.

  • 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.


RoHS Compliant Models Available

RoHS (Restriction of Hazardous Substances) Directive:
Directive on restriction of the use of certain hazardous substances in electrical and electronic equipment (2002/95/EC).
The RoHS Directive prohibits the use of six chemical substances in electrical and electronic products sold in the EU member states. The six controlled substances are: lead, hexavalent chromium, cadmium, mercury and two specific brominated flame-retardants (PBB and PBDE).
