The BLV Series R Type brushless DC motor and compact driver not only reduces the size and weight of the original BLV Series driver but offer an upgrade to the motor as well.  This blog post uses videos to explain the features offered by the BLV Series R Type.

The original BLV Series has been adopted mostly by AGVs that convey objects along magnetic tapes.  Since the demand for automation is increasing due to a decreasing labor force, we've been seeing growing demand for smaller and smarter mobile robots from various types of industries.  The smaller and lighter BLV Series R Type is equipped with features and functions that can upgrade your robot and simplify designs.  

BLV Series - R Type

At a glance:

  • Output Power: 100 or 200 W
  • Input Voltage: 24~48 VDC
  • Gear Types: Parallel shaft, hollow shaft flat, and round shaft (no gear)
  • Torque Output: 45 oz-in to 470 lb-in.
  • Speed Range: 1~4,000 RPM
  • Options: electromagnetic brake, flange drive adapter, cables, couplings, and mounting bracket

BLV Series R Type motor and driver redesign


The BLV Series R Type offers either a 100 W or 200 W brushless DC motor with a compact yet fully functional driver.  Both the motor and the driver design have been updated from the original BLV Series.  The R Type is ideal for compact robot designs.  Upgrades include better speed regulation, smoother performance, positioning capability, and network communication protocols, such as Modbus RTU and CANopen.

Motor Size Reduction

Compared to the original BLV Series, the BLV Series R Type motor is shorter and lighter.  Here is a comparison of a 100 W motor.

Hollow Shaft Flat Gear Motors for Small Footprints

By using the hollow shaft flat gear motors from the BLV Series, a compact transportation robot with narrow tread width can be designed to increase operational efficiency in tight spaces.

Hollow Shaft Flat Gear for Low Platform Designs

The hollow shaft flat gear and flange drive adapter can also help with low platform robot designs, which run under product carts.   Both side and top surface mounting options are available.

The R Type Driver: Tiny But Powerful

Compared to the original BLV Series driver, the BLV Series R Type compact driver offers a significant reduction in volume and mass.  It's one of the smallest drivers in the industry.  The R type driver also offers network compatibility with Modbus RTU and CANopen as well as improved programming and advanced features for battery operated robots.

High Resolution Motor Sensor Improves Performance

The new high resolution motor sensor from the BLV Series R Type offers many upgrades in performance; including better starting and stopping performance for positioning operations and smooth operation at as low as 1 RPM (at the motor shaft).

ID Share Mode Eliminates Communication Lags

To avoid communication lags between multiple axes, the BLV Series R Type offers an ID Share Mode function that enables synchronized communication between master and slaves.

Advanced Data Monitoring Functions

Various types of monitoring are possible.  For example, you can monitor the main power supply voltage and power consumption.  The dedicated support software also offers a continuous trace monitor that can help visualize issues before they happen.  Two gigabytes of storage is available (about one day).
