### The role of electronic drives in the performance of DC electric motors Electronic drives play a vital role in controlling and improving the performance of DC motors. These devices help to accurately adjust parameters such as speed, torque and direction of rotation of the motor, thereby increasing the efficiency and accuracy of electrical systems. Here we take a closer look at the role of electronic drives in the performance of DC motors. #### speed control One of the most important tasks of electronic drives is to control the speed of DC motors. Drives vary the voltage or current applied to the motor using various techniques. For example, PWM (Pulse Width Modulation) controllers adjust the average applied voltage by changing the width of the pulses sent to the motor, which leads to a change in the speed of the motor. This feature allows users to precisely and continuously control the engine speed. #### Torque control Electronic drives can also control motor torque. The torque is directly dependent on the current passing through the motor.
