Frequently Asked Questions
Common questions about the VRA / VRB
What applications is the VRA series best suited for?+
The VRA series is optimised for compact embedded applications in industrial robotics, automotive accessories, smart home devices and logistics automation — anywhere a reliable, compact DC motor is required.
How do I control the speed of the VRA motor?+
DC permanent magnet motors are inherently variable speed. Vary the supply voltage or use a PWM speed controller for precise speed control. Speed is approximately proportional to applied voltage.
Is an encoder option available?+
Encoder options may be available for closed-loop speed control. Please contact us with your feedback and control requirements for available configurations.
Can I get custom voltage and shaft specifications?+
Yes. Custom voltage, shaft diameter, shaft length and winding specifications are available for OEM orders with flexible MOQ.
How does the VRB differ from the VRA?+
The VRA and VRB series are complementary models with different frame sizes or specification profiles to cover different load and integration requirements. Contact us with your load data and space constraints for the correct model recommendation.
Can the motor direction be reversed?+
Yes. Reverse the polarity of the DC supply to reverse motor direction. For automated directional control, use an H-bridge motor driver or relay circuit.
