The Field-Oriented Control (FOC) method is a motor control strategy that orients the stator current vector in a rotating reference frame of the machine.
This technical note explains how to implement speed control for an electric motor. First, the note introduces the general operating principles of motor speed control,…
This note covers the rotor field-oriented control of an induction machine and its implementation on a user-configurable voltage-source inverter.
This note covers the V/f control of an induction machine and its implementation on a programmable drive inverter.
This note covers the I-f startup method for speed sensorless motor control and its implementation on a programmable power converter prototype.
This technical note addresses the sensorless control of motor drives using a back-EMF sliding-mode observer. The technique allows speed and position estimation of a Permanent…
What is the space vector modulation technique (SVM) and how does it work? To answer these questions, this article introduces first the notions of active…
What is the difference between Space Vector (SVPWM) and Sinusoidal Pulse Width Modulation (SPWM)? This article presents the advantages of the SVPWM technique over SPWM…
The incremental encoder interface (INC) block decodes the A, B, Z signals from an incremental encoder for motor drive applications. The B-Box supports up to…
