A DC motor uses direct current as a power source and consists of components like a split ring commutator, permanent magnet, and brushes to convert electrical energy into rotational mechanical energy. An AC motor uses an alternating current power source and a slip ring commutator to allow the current direction in its coils to change, enabling the rotor to rotate continuously in one direction within a magnetic field. Both motor types convert input electrical power to output rotational motion but differ in their power sources and commutation methods.
Differences between dc and ac motors presentation
- 1. DIFFERENCES BETWEEN DC AND AC MOTORS
- 2. SIMPLE DC MOTOR • Has a direct current as a power source, such as a 1.5V dc battery for example. • Its function is to convert electrical energy to mechanical energy that can perform work. • Consists of various components such as a split ring commutator, permanent magnet, brushes, a coil, a direct current power supply and current carrying wires.
- 3. FLEMINGS LEFT HAND RULE:
- 5. SIMPLE DC MOTOR EXPLAINED • Due to the forces in the motor , torque is produced which turns the loop. • After a 90 degree turn, the coil comes to a vertical position, where there is no force acting on it, but due to the coils moment of inertia the coil continues to rotate. • After a 180 degree turn the position of the conductors has been changed. • Because of the split ring commutator one can conclude from the previous illustration in this case, at the North pole an upwards force will always be produced and at the South pole a downwards force will be produced.
- 9. SIMPLE AC MOTOR • Has an alternating power source. • Similar to a DC motor, a AC motor also converts electrical energy to mechanical energy. • A simple AC motor consists of various components such as a slip ring commutator, an AC power supply, a permanent magnet, and current carrying wires.
- 10. SIMPLE AC MOTOR
- 11. SIMPLE AC MOTOR • One of the main difference a AC motor has from a DC motor is that an AC motor has a slip ring commutator which allows the current to continuously change direction in the coil of the ac motor. • Another difference is that the power supply supplies alternating current instead of a direct current which allows the rotor to rotate in one direction in a magnetic field. • The ac power supply can be produced by a device called a AC generator.
