Pulse width modulated control of electric motors (PWM) is a technique in which the width of the voltage pulses supplied to the motor is modulated. By varying the duration of each "ON" pulse compared to the total duration of the cycle (ON + OFF), one can effectively control the average voltage supplied to the motor.
The LTTsmart's capabilities are particularly interesting when it comes to PWM control of electric drives. The physics behind this happens in the steep switching edges, in which the LTTsmart captures sufficient measured values to precisely determine all key performance indicators. The combination of high-voltage channels on the one hand and a high resolution of 24 bits and high sampling rate of up to 4 MHz per channel on the other makes the LTTsmart power meter perfect for precise and fast #measurement requirements.
So if you want to control electric motors, pulse width modulated control is a powerful way to control motor power efficiently.
