NORD DRIVESYSTEMS expanded its IE5+ synchronous motor line with the new 112 frame size. The new SK 112 motor size extends the power of compact IE5+ permanent magnet synchronous motors to 15.0 hp.

IE5+ permanent magnet synchronous motors (PMSM) from NORD DRIVESYSTEMS deliver high energy efficiency. Permanent magnet technology uses high-strength permanent magnets to create a constant magnetic field, eliminating the need for external excitation and resulting in extremely high efficiency of up to 95%, high power density, and significant energy savings.

NORD offers IE5+ motors in sizes 71, 90, and newly released, size 112, extending the power range from 0.5 to 15.0 hp and torque up to 387 lb-in.

Inside the IE5+ motor range

IE5+ synchronous motors deliver constant torque and efficiency over a wide speed range, even at partial load and low speeds. This enables reduced system variants, minimized administrative expenses, and leaner manufacturing, logistics, storage, and service processes.

Ventilated versions (TEFC) are available in all 3 frame sizes and feature a finned housing that provides advanced heat dissipation, ideal for continuous duty intralogistics applications. Smooth body, non-ventilated versions (TENV) are available in motor sizes 71 and 90 and offer a corrosion-resistant option in hygienic environments such as food and beverage applications. IP69K Protection Class is additionally available with TENV versions for an easy-to-clean surface that can withstand harsh environments.

IE5+ motors significantly exceed the highest defined energy efficiency class, considerably reducing their energy consumption and CO2 emissions.

In addition to considering energy efficiency, the motors also consider material efficiency. They feature an innovative 8-pole Interior Permanent Magnet (IPM) design that reduces the number of active motor parts, resulting in material savings regarding the sheet metal and magnets. The stator can also be manufactured with single-tooth winding, reducing the use of copper in the winding head.

Drive solutions from NORD are always configured to individual application requirements, creating the ideal system for each project. IE5+ synchronous motors further expand their system capabilities with compatibility across their product range of gear units and electronic control projects.

The motors are equipped with a standard incremental encoder and feature additional options including an integrated mechanical brake, motor connectors, absolute or magnetic encoders, and various flange mountings for gear unit attachment as well as direct mounting. No matter the application, IE5+ PMS motors help users achieve increased operational efficiency, reduced total cost of ownership, and a fast return on investment.

NORD also develops and produces a wide range of drives for more than 100 industries and gear units for torques from 10 Nm up to over 282 kNm. It also supplies electric motors in the power range of 0.12 kW to 1,000 kW, as well as the required power electronics with frequency inverters of up to 160 kW.

In February, NORD also announced that it now offers digital twins for system development. Based on a myNORD configuration, users can request individually created drive systems as simulation models.
