FAQ
  • What is the no load current of a brushless motor?

    The no-load current of a brushless motor is defined as the current the motor draws, with no load applied, at a specific voltage. The no-load current is measured in Amps and denoted “Io.” The key point here is that the current is measured at a specific voltage.

  • What is the voltage on no load?

    It is the potential difference (Voltage) across the terminals (Phases) before any load is connected or plugged in. For example, if you took a long power cord (Say 30 meters) to the bottom of the garden and before connecting anything you took the voltage reading this would be the no-load voltage.

  • What is the no load current of a 15kw motor?

    The no-load current of an SQ induction motor as a thumb rule can be assumed to be around 30 to 40% of full load amps. It means the motor consumes 30 to 40% of full power in no load condition. So a 15kw motor will consume around 5kw power when run in no load condition.

  • What is a no load test?

    The open-circuit test, or no-load test, is one of the methods used in electrical engineering to determine the no-load impedance in the excitation branch of a transformer. The no load is represented by the open circuit, which is represented on the right side of the figure as the "hole" or incomplete part of the circuit.

  • Why no load test at rated voltage?

    If the voltage deviates from the rated value, since the magnetic induction in the transformer core is in the saturation section of the magnetization curve, the no-load loss and no-load current will change sharply. Therefore, the no-load test should be carried out at the rated voltage.
