Thanks to the motor drive, we protect our motor and system against many faults such as overcurrent, overvoltage, earth fault, external fault, motor heating fault. As we provide system and motor protections thanks to these parameters, additional costs such as thermal switch, motor protection relay will be used in our system for prevention. Energy savings can also be provided by motor inverters. In applications such as Fan and Pump, which do not require large torque, the speed adjustment of the motor drives is reduced by up to 70% and the money paid to the driver and other equipment compensates for itself in a short time..
