Oriental Motor enhances motor driver design

The BLV-R series of BLDC motors and drivers from Oriental Motor has been redesigned to improve parameters such as speed and stability, while significantly reducing size and power consumption.

The BLV-R series of BLDC motors and drivers is based on Oriental Motor’s BLV series. The new BLDC series offers improved positional feedback, DC voltage range, STO (safe torque off) ability, speed range and speed stability. It is also engineered to be smaller and to have lower power consumption.

The BLV-R series is specifically designed towards the automated guided vehicles (AGVs) market and other new and emerging applications.

Gearhead options are a parallel shaft or hollow shaft and gear ratios range between 5:1 to 200:1 to deliver a wide range of output speed and torque options. Operation speed can be as low as 1r/min. Output power for the BLV-R series is 60W, 100W or 200-400W, depending on the variant and torque from 0.43 to 108Nm, depending on the motor and gearhead combination.

The usable voltage range is 15VDC to 55VDC, and speed control range is 1:4000rpm, enabling a range of voltage changes. The wide input compensates for any voltage drops within the battery of, for example, an AGV, allowing it to continue operation without intervention. In the event of temporary battery voltage increases, for example from regenerated energy, normal operation is maintained.

An integrated encoder provides improved positional feedback. Positional resolution is set at 0.01° but is fully adjustable in the driver parameters for higher resolution, high speed and high accuracy performance. The increased control can be used to perform tight turns and accurate manoeuvring.

Improved torque control down to 1rpm increases movement accuracy. Feedback also means the motor can be used in tensioning applications where the driver will continuously maintain a set torque and not aim to maintain a speed.

An ATL function introduced to the BLV-R series allows the motors to deliver up to 300% of their rated torque continuously (only limited by the thermal alarm cut-off). This allows equipment to negotiate slopes and ramps using more torque as and when needed.

A proprietary ID Share Mode, developed by Oriental Motor, allows commands to be sent to multiple motors simultaneously for accurate movement and smooth operation even in confined areas.
