WebJan 18, 2016 · Figure 2: Bidirectional brush DC motor control using an H-bridge. (Source: Microchip) For speed control, a pulse-width modulated (PWM) signal is used to generate an average voltage. The motor winding acts as a low-pass filter so that a high-frequency PWM waveform will generate a stable current in the motor winding. WebStator and rotor of acceptance machines – Armatures of both coordinated and DC machines are examples of circulated windings. Closed Motor Winding There is a closed path in that if one starts from any point on the winding and traverses it, one will end up back where one started. DC and AC commutator machines are the only machines that use this term.
WebStart assessing winding resistance by looking for the motor’s nameplate or checking the manufacturer’s instructions that came with the motor. One of these places should show the motor’s optimum winding resistance level. If the measured numbers show a significant discrepancy from the optimum level, rewinding is probably necessary. 3.
