An electric motor designed for industrial use differs from its domestic counterparts in design philosophy: the goal is not maximum comfort but predictable, uninterrupted operation under continuous load. The motor that turns a pump, a hoist or a conveyor on a production line is sized to deliver the same performance for years.

What Sets an Industrial Motor Apart?

Three-phase asynchronous motors have become the industrial standard thanks to their rugged construction and low maintenance needs. The squirrel-cage rotor design, with no brushes or commutator, minimises the number of wearing parts, which translates into long service intervals and high uptime.

Matching Power, Speed and Torque

Correct motor selection begins with the power and speed the load demands. On a 50 Hz supply a 4-pole motor runs at 1500 rpm, a 2-pole at 3000 rpm and a 6-pole at 1000 rpm. Low-speed motors suit high-torque mills and mixers, while higher-speed models are chosen for pumps and fans.

Efficiency Class and Running Cost

The IEC 60034-30-1 standard grades efficiency from IE1 to IE5. IE3 Premium and IE4 Super Premium motors carry a slightly higher purchase price, but the energy they save quickly pays it back in plants that run continuously.
