40 Ohm 300W Brake Resistor for CNC Inverter and Drive
The 40 Ohm brake resistor is an important component in motion control systems, inverters and servo drives, which is responsible for absorbing the return energy of the motor when it slows down or stops. This energy is converted into heat and prevents the DC bus voltage from increasing, which helps to ensure more stable operation of the equipment and reduce errors caused by overvoltage.
