Beckhoff Automation’s AM8800 stainless steel servomotor series feature one motor cable instead of the two used in common motors, and the encoder information is transmitted digitally via two cores of the motor cable. The stainless steel motors can be used in extremely harsh or corrosive environments and are well-suited for use in the food, chemical and pharmaceutical industries, the company says.
The servomotors feature an all-stainless-steel housing in AISI 316L, designed according to FDA guidelines, and a stainless steel motor shaft. Three sizes are available. The power range extends from 1 to 8 Nm standstill torque. The motor flanges are implemented in B5 form and are compatible with the AM8000 series flanges. The servomotors are equipped with a sensor for temperature monitoring, which passes the data on to the drive via the single cable. The motors can be intelligently controlled in relation to its temperature.
According to the company, the stainless steel housing is resistant to scratches and mechanical damage. Connection of the stators to the housing has been optimized, which minimizes power loss. Equipped with IP 67 protection (IP 69K rating optional), the motors can be cleaned with high-pressure cleaners. Stainless steel cable glands ensure permanent sealing integrity. The motors can be equipped with a sealing air connection to prevent the formation of condensation inside the motor. They can also be equipped with a holding brake or a multi-turn encoder, depending on the application requirements.
