WebYou're right, not available on 525. Cameltron303 • 1 yr. ago. You should use a braking resistor whenever your motor might end up in the Regen quadrant. i.e. having to resist a load over speeding it during normal operation. A mechanical brake won't help you with that. WebThe braking resistor is switched on by a separate control unit, activated by a sensor which is monitoring the voltage level of the DC bus and switching on the braking … Web20 jun. 2024 · Resistors are electrical components that oppose the flow of either direct or alternating current. They can be used to protect, operate, or control circuits. In combination with other components, resistors can also be used to make electrical waves into shapes suited to the designer's requirements. immediate job openings in baltimore md
