  • Page 9: Product Description

    Product description Product description The PMCtendo SZ synchronous servo motors have a very short design made possible by using optimal winding technology. This allows for the stator windings to be manufactured with the highest possible copper fill factor. This technology and other optimizations of the mechanics make it possible to shorten the motor length by roughly half without negatively impacting performance.

    Product description Thermal winding protection The PMCtendo SZ synchronous servo motors have thermal winding protection that protects the stator winding from damage during constant overload. The PMCtendo SZ motors are equipped with a PTC thermistor. If the motor temperature reaches a critical value, the resistance of the PTC resistors increases abruptly and thereby indicates the overload of the motor.
