Permanent Magnet vs Electromagnet in Commercial Electric Motors
In commercial electric motors, a permanent magnet is not used to rotate the armature. Instead, an electromagnet is used to create the magnetic field necessary for the motor to function efficiently.
Explanation:
- Electromagnet: Commercial electric motors use an electromagnet to rotate the armature. This electromagnet is created by passing an electric current through a coil of wire, which generates a magnetic field. This magnetic field interacts with the permanent magnets in the motor to produce motion.
- Permanent Magnet: While permanent magnets can be used in some types of electric motors, they are not typically used in commercial electric motors. Permanent magnets can be less versatile and may not provide the level of control required for many applications.
- Efficiency: By using an electromagnet instead of a permanent magnet, commercial electric motors can achieve a higher level of efficiency and control. The electromagnet can be easily adjusted by varying the current passing through the coil, allowing for precise control over the motor's speed and torque.
- Soft Iron Core: Commercial electric motors also use a soft iron core on which the coil is wound. This core helps to concentrate and strengthen the magnetic field generated by the coil, improving the motor's performance.
In conclusion, commercial electric motors do not use a permanent magnet to rotate the armature because an electromagnet provides better efficiency, control, and performance for a wide range of applications.
