Description

This lecture explores the behavior of a DC motor depending on the voltage supply, demonstrating the effects of varying the voltage supply on the motor's torque characteristic and how to implement a variable voltage supply. It also discusses the influence of current limitation on the motor's torque characteristic, historical methods of varying motor voltage using a variable resistor, and modern electronic solutions like transistors and H-bridges to achieve variable voltage supply and bidirectional current flow.
