Does An Electric Motor Draw More Current Under Load at Frances Stepp blog

Does An Electric Motor Draw More Current Under Load. As your load increases and you need more torque, the. While the motor is rotating, i hold the motor by hand so that it stop. A motor under load runs slower, the impedance is lower, and higher current, i.e. This is because when running, it is also acting as a generator, creating an emf which opposes the. As an electrical engineer with more than a decade of practical experience, i can confidently say, that electric motors draw more current when dealing with heavy loads (overloading), voltage drop, mechanical issues (like bad bearing), or internal electrical issues (internal short circuit). As more and more load is applied to the motor, the motor slows reducing its back emf allowing more current to flow, producing more torque. In general, on a dc motor, speed is proportional to voltage and torque is proportional to current. In fact, typically a motor will draw much more current when stalled than when running. What the video demonstrates is that the dc motor draws less amps when operating under no load than it draws when it is stalled. Jan 15, 2015 at 14:28. The fact that a device is under load actually directly means that the device is simply using power or current from the supply. I have a small motor connected to dc source, and use the ampere meter to survey the current through the motor.
