there are drawbacks when direct starting a motor:
High inrush current: Heat, flicker risks, energy and installation costs
- Noise, arcs: Short control lifetime and high maintenance costs
High transient torque: Excessive wear of the coupling parts leading to maintenance costs
All of these disadvantages can lead to quality problems during production.
Thanks to their size and high adaptability, solid state relays are more and more popular to control motor loads.
One of the main advantages of using power electronics is that the numerous control modes can easily perform thanks to very fast response time, and computing power of microprocessors.
