Answer / mukesh sharma

we can check motor impedance & type of connection (whether
it is operating in star or delta connection) we can find out
the approximate power of the motor.
then by provability of motor power we can find out the
actual power of the motor.

Answer / Sharib Ahmad

To find the horsepower (H.P.) of a motor without any rating using a multimeter:
1. Measure the resistance (R) in Ohms (Ω).
2. Apply the formula: H.P. = (T * π * N) / 30,000, where T is Torque in Newton-meters and N is RPM (Revolutions Per Minute).nNote: The torque value for DC motors can be calculated using Ohm's law: T = K * I^2 * R, where K is the motor constant.
