Dynamic brake resistor

WebDynamic braking is the method of stopping the motor by dissipation of heat in the resistor. When a motor is driven by VFD, the motor acts as a generator when the actual speed of the motor is more than the VFD frequency. The generated energy dissipates in the resistor ( Dynamic braking resistor) and it leads to braking of the motor. WebDynamic Braking Resistor is a high power / wattage resistor used by a electric motor to assist in the process known as dynamic braking. DC motors, unlike AC motors, act like …
