NORD Gear Corp.’s Smooth Surface Motors are now available for the North American market and for export to key global markets, including both the HM and HMT series.
HM Series motors are made from a high-strength, naturally corrosion-resistant aluminum alloy, and can be supplied with a variety of protective coatings and finishes. Aluminum housings are particularly beneficial in car washes and food and beverage applications as they offer better heat dissipation, effectively reducing internal motor or gear unit operating temperatures while increasing component life and reliability compared to cast iron or steel.
HMT Series motors are supplied with NORD’s exclusive NSD Sealed Surface Conversion System, and they can be offered as part of a wide range of integral gearmotor or motorized reducer solutions complete with NSD. The product offering includes four continuous-duty, premium, efficient motor sizes ranging from 0.5 to 1.5 hp with an IEC B14 flange mount, and many options to configure as a NORD integral gearmotor assembly. Motor options are varied and include brakes, thermal overload protection, space heaters, potted terminal boxes, condensation drain holes and connectivity solutions.
NORD Smooth Surface Motors are readily available and configurable with the NORDBLOC.1 Series Helical-Inline, 93.1 Series (2-Stage) Helical-Bevel and the SMI Series Worm gear units. Integral gearmotor options are available with a wide array of gear ratios and flexible mounting options. The motors and gear units combine durability and compactness in a cost-effective, lightweight and easy to clean solution.
They are ideal for applications where sanitation and cleanliness are essential as well as applications in damp and wet environments. NORD NSD product solutions have been field-proven to rival more costly stainless steel motors and options. NSD is resistant to blistering, flaking and peeling, offers corrosion resistance across a wide pH range, and a surface that is 1,000 times harder than paint.
