Permanent magnet motors have _____ efficiency than conventional field-wound motors.
A) higher
B) lower
Permanent Magnet Motors
Electric motors that utilize permanent magnets to generate the magnetic field within the motor, rather than an electrical coil.
Field-wound Motors
Electric motors where the magnetic field is generated by winding wire around a core to create electromagnets, typically adjustable for speed control.
Efficiency
The ratio of useful output of a system to its total input, often expressed as a percentage, indicating how well the system converts input energy into output work or desired form of energy.
- Elucidate the transformation of electrical energy into mechanical energy and its reverse process.
- Calculate and understand the effects of voltage, resistance, and magnetic fields on motor operation.
