What is a direct torque control?

Direct torque control is the method of optimizing and maintaining normal operations, usually within the AC engine (AC). There are several applications for this type of control, usually in machines that require consistent and reliable torque. Compared to other methods of AC motor control, several advantages and several disadvantages have direct torque control, although it depends on the application. Some technological options are allowed and further increase this and other variable frequency units - machines usually responsible for controlling the electricity supplied to the engine. Specifically, the main variable voltage and current are measured. Magnetic flow and engine torque can be derived from these values. Once these measurements have been taken, the electric current that is supplied to the engine is adjusted to maintain optimal torque and flow ranges if necessary. Most often, direct torque control will be implemented on three -phase AC engines, although itNo designs can often integrate similar processes. Early experiments with direct torque control have placed systems in locomotives and direct torque control can now be used in electric cars.

The

advantages of this kind of inspection generally stem from consistent measurements and modifications that are performed to optimize operations. Ideally, any adjustments will be made almost immediately. This can increase the efficiency of the engine overall and help reduce energy loss. In addition, this type of inspection can reduce the engine mechanism, further increase efficiency and even reduce sound noise at low speeds.

The disadvantages of these systems often begin with incorrect measurements. For example, there are often measuring errors at low speeds, which can lead to incorrect adjustments and loss of efficiency. Incorrect measurements can also occur at high speeds and in the entire spectrumMoments. As a result, high -quality measuring and monitoring equipment is usually required.

High -speed computer technology plays an important role in efficient direct torque control. So many quick calculations are required that extremely fast computers and other digital controllers are often necessary to make the correct modifications in time. In addition, speed and position sensors are often required, especially in low -speed applications.
