ABB drives, Technical guide No. 1 Direct torque control ...
library.e.abb.comThe advantage of DC drives is that speed and torque - the two main concerns of the end-user - are controlled directly through armature current: that is the torque is the inner control loop and the speed is the outer control loop (see Figure 1). Advantages – Accurate and fast torque control – High dynamic speed response – Simple to control
Pulse Width Modulated (PWM) Drives - Rockwell Automation
literature.rockwellautomation.comoperating speed range for volts/hertz drives is typically around 20:1. As the load is increased, the motor speed drops off. This is not an indication of starting torque. This only shows the ability of the drive to maintain torque output over a long period of time. The next type of control was developed to address some of these concerns.
