WebSep 27, 2024 · Current increases when voltage increases (or average voltage value in the case of PWM). So, to control speed, we can choose torque, current, or voltage as the controlling input. Out of these, voltage signal is easiest to measure, compare, generate and apply. The first figure seems to do just that.

In a brush (see Figure 5) or a brushless dc motor (see Figure 6), the working point (speed and torque) of an application can vary. The amplifier’s role is to vary the supply voltage or the current, or both, to achieve the desired motion output. There are often two different ways to vary the voltage or the current: 1. … See more Unlike brush dc motors, in which commutation is made mechanically by brushes, brushless dc motors are electronically commutated. This means the phases of the motors are energized and unenergized in … See more A dc motor is characterized by an inductance L, a resistance R, and a back electromotive force (back-EMF) E in series. The back-EMF is a voltage caused by the magnetic induction (Faraday-Lenz law of induction) that … See more PWM will lead to current rise and fall at each cycle. The variation between the minimum and the maximum value of the current is called the … See more The current ripple will increase the RMS (root mean square) current value, which is the value considered for Joules losses calculation.
