Nord Drivesystems introduces new smooth-surface motors for high-hygiene applications. The three-phase induction motors without cooling fins are especially well-suited for applications in the food and beverage industry, since they are easier to clean than finned motors.

Manufactured from aluminum, the motors can be finished with the nsd tupH surface treatment for a corrosion protection level similar to that of stainless steel drives and without the danger of flaking that occurs with coatings.

The Nord-developed treatment is compliant with FDA Title 21 CFR 175.300 requirements. Non-ventilated and ventilated variants with ingress protection of at least IP66 are available, initially in sizes 80, 90, and 100 with motor power output from 0.37 to 2.2 kW. Efficiency levels corresponding to IE2 or higher ensure resource-friendly operation. Brakes and full thermal motor protection (bimetal temperature sensor or thermistor temperature sensor) can be optionally ordered in addition to incremental encoders. The smooth surfaces enable rapid and easy cleaning and are thus ideal for hygienic solutions, especially in combination with washdown gearboxes from Nord. The new motors are fully compatible with the entire Nord drive program, supporting and ensuring high versatility for efficient drive configuration.
