Due to the great development of AC power systems, AC motors have become the most commonly used motor. The AC motor is divided into two categories: synchronous motor and asynchronous motor. The principle is to provide a single-phase or three-phase AC power to the motor, in order to form a rotating magnetic field, so that the motor rotates. ITECH's IT7300 series has a built-in power meter function that allows real-time access to parameters during motor operation. The parameters include voltage and current RMS, power factor, active power, apparent power, frequency, and peak current, making test wiring easy.
