A voltage clamp protects a RoboClaw motor controller and its power supply from regenerative voltage spikes. This tutorial shows how to wire and configure a voltage clamp using either the BasicMicro VClamp board or a discrete MOSFET circuit.
Ground Path Issues
When using a motor controller improper grounding can cause damage to the motor controller and also to devices attached to it.
Motor Controller Protection: Diodes, Clamps, and Pre-Charge Resistors
Motors generate a regenerative voltage spike when they stop or slow quickly, which can damage a motor controller. This guide covers how to protect a controller with a bypass diode, a voltage clamp, a pre-charge resistor, and the maximum voltage setting.
