Drawbacks of AC Electric Motors
AC electric motors have a colossal number of benefits over customary burning motors and a few benefits over DC electric motors. Overall electric motors have less moving parts, so they are simpler to keep up and have an any longer life expectancy than a burning motor. Electric motors don't need fuel, motor oil, or battery administration. The rundown continues forever, yet when is it disadvantageous to utilize an electric motor? Here are a couple of circumstances to consider.
1 AC Electric Motors Are Complex
Albeit both AC Electric motors and DC electric motors are far less difficult than burning motors, AC electric motors are more intricate, have more parts, and require complex controls to deal with the flow. Force converters in AC drives are likewise more mind boggling. This implies that a genuine AC electric motor repair will cost in excess of an ignition motor or DC electric motor repair.
2 Speed is Difficult to Control
Controlling an AC electric motor's speed is troublesome in light of the fact that the speed is changed by changing the recurrence, which isn't in every case simple to do.
AC electric motors run at a steady speed for the whole stacking range. Any endeavor to control the speed of an AC motor reductions the effectiveness and brings down the force factor.
3 Poor Starting Torque
Most AC electric motors have low beginning force. However, a considerable lot of the most well-known applications require high beginning force. A portion of these applications include:
- Most vehicle motors
- Starter motors
- Siphon motors
- Link winch motors
- Oil well penetrating hardware
- Windshield wiper motor
Burning motors and DC electric motors turn out better for high force power needs.
4 AC Electric Motors Are Less Efficient
AC electric motors are less effective than DC electric motors since AC motors lose proficiency as a result of the optional attractive field created from the lasting magnets as opposed to copper windings. This adds up to an effectiveness loss of up to 30% in an AC motor contrasted with a DC electric motor.
5 AC Electric Motors Are Not Self Starting
AC electric motors expect help to get going. Though burning motors and DC electric motors are both self-beginning, an AC motor necessities some beginning gear, for example, a delicate starter or variable recurrence drive to find a good pace.
