How can i calculate the power of an electric motor?

Question

Julia Aguilar · Accepted Answer

Power is #V I#

Determine the voltage needed to run the motor and the current it uses when there is no load or when there is a specific load.

The product of voltage and current is called power.

You should elaborate on the motor in more detail as your question is quite general.

Benjamin Asiedu · Answer

undefined The power of an electric motor can be calculated using the formula: $ P = VI $, where $ P $ is power in watts (W), $ V $ is voltage in volts (V), and $ I $ is current in amperes (A). Alternatively, if you know the resistance $ R $ of the motor, you can use the formula: $ P = \frac{{V^2}}{R} $.

William Audy · Answer

undefined To calculate the power of an electric motor, you can use the formula:

$$ P = VI $$

Where:
- $ P $ is the power (in watts),
- $ V $ is the voltage (in volts), and
- $ I $ is the current (in amperes).

Alternatively, if you know the resistance ($ R $) of the motor and the current ($ I $), you can use the formula:

$$ P = I^2R $$

Or if you know the voltage ($ V $) and the resistance ($ R $), you can use the formula:

$$ P = \frac{{V^2}}{R} $$

These formulas allow you to calculate the power output of an electric motor based on the provided parameters.
