Advantages and disadvantages of electric motors
6 March 2022
The electric motor is a device that converts electrical energy into mechanical. It is the interaction between these fields. Thereby runs the machines or devices. So Basically, these devices produce the force to convert the energy, thus called motor. Based on this function of shifts between the two fields, there are two main types of motors. One which takes alternating current, AC motor. And the other takes direct current, thus named DC motor. Both come with advantages and disadvantages.
The Dc electric motor has excellent speed control because it connects directly to the Motor field; the precise voltage control is faster. It is easy to design by attaching to a magnetic field. It has cheap drive designs( silicon rectifiers, pulse width modulation) modulated by pressing the knob. The dc motor’s high maintenance, care, and vulnerability to performance in different environments make it disadvantageous. Ac motors function on stator and rotor mode. Its low cost, simple design application makes it worthy of being induced by most appliances such as Air condition, fans, and vacuum cleaners. It has a fixed number of wading sets that determine its base speed, so the speed of the motor is mediated. Due to its design, it has fewer maintenance issues. Once launched, it could run for years and years.
One of the significant drawbacks of AC motors is that it does not run on low power compared to DC motor, which is runnable. It produces the back electromotive force, which reduces the current in the loop, thus slowing down the motor. These were pros and cons related to the AC and DC motors. In general, we can say that the cost of electric motors is much lower than fuel engines when we look around at the use of most AC motors. It has few moving parts, and thus it has more lifespan of up to 30,000 hours. Electric motors are automotive and highly efficient; this automated start and stop function allow better maintenance services.
Automobile commercial vehicles using electric Motors in their engines help reduce pollutants emissions. It makes them more efficient in their role and environmentally friendly compared to traditional engines. But we do have the other side of the story: many large electric motors are not easily portable; they require expensive line extensions in remote locations. To end, we can say that all types of electric motors come with varied benefits and imperfections; we need to use them wisely.
