DC MOTORS AND GENERATORS
PublicResourceOrg・2 minutes read
Rotating electrical machinery in military equipment relies on AC and DC motors and generators, with DC generators producing pulsating direct current and different types of DC generators having unique characteristics for voltage and current regulation. DC motors, like generators, use electromagnets for the field and different windings affect torque and speed control, with shunt, series, and compound motors offering varying starting torque and speed regulation capabilities.
Insights
- The functioning of military equipment heavily depends on the proper operation of rotating electrical machinery, with AC and DC motors and generators being crucial components that generate electromotive force (EMF) through conductor movement in a magnetic field, influencing factors like magnetic field strength, conductor length, and velocity.
- DC generators convert rotary motion into pulsating direct current (PDC) using commutators, which can be optimized to reduce ripple by increasing loops and commutator segments; DC motors, utilizing electromagnets for field control, vary in characteristics like torque and speed regulation based on different field winding configurations, such as series, shunt, and compound motors, each designed for specific applications within the machinery.
