Remember, motor feeder conductors must be protected against the overcurrent that results from short circuits and ground faults but not those that result from motor overload. When sizing the feeder protection, be sure to include only the motors that are on the same phase. Refer to Fig. 5 for this sample motor feeder protection calculation.

For a 1-phase supply with power rating in kilowatt (kW): For a 1-phase supply with power rating in horsepower (hp): Note that the motor rated full load current is specified on the motor datasheet and stamped on the motor nameplate. However, this calculator is useful when only the motor rating is available and an estimate of the current is required.

The speed of Induction Motors and Reversible Motors vary with the size of the load torque. So, the selection should be made between the rated speed and the synchronous speed. There can be a difference of continuous and short-term ratings, due to the difference in motor specifications, despite the fact that two motors have the same output power.

Rule#1: The feeder or service neutral load Basic Calculation As per NEC section 220.61(A), The feeder or service neutral load shall be the maximum unbalance of the load determined by article 220. The maximum unbalanced load shall be the maximum net calculated load between the neutral conductor and any one ungrounded conductor.

If you can measure the voltage and amps flowing into the motor leads: (single phase) Amps x volts = VA, assume the Power factor is 0.8 so the KW is (VA/1000) x 0.8 on three phase, assuming balanced line currents, multiply by sq rt 3 (1.732). That

Usually for small motors maximum power is at 50% of stall torque (approximately 50% of no load speed). Maximum efficiency may be 10-30% of motor stall torque (70-90% of no load speed). While it is technically better to follow the same format and create similar curves for your motor it is not absolutely necessary for a good science project.
