NettetIt becomes less and less leading and then becomes more and more lagging as shown in the figure above. Thus, if the load on a synchronous motor is increased the following … Nettet4. jun. 2024 · A motor converts electrical power into mechanical power. Electrical power = voltage x current. So if the motor is run on lower voltage then to deliver "the power expected of it" it must draw more current. But that doesn't mean it will always work at constant power output regardless of voltage.
