Permanent magnet motors can eliminate belts and chains

Permanent magnet motors can eliminate belts and chains The SyMAX series of permanent magnet motors available from Regal incorporates a radial flux design which delivers significantly higher torque, higher efficiency and increased power density when compared to traditional induction motors. They have the potential to eliminate drive belts, chains and gearboxes in certain applications.

SyMAX FHP (fractional horsepower) motors are built to a totally enclosed fan-cooled (TEFC) or totally enclosed non-ventilated design, and they are also said to be lighter and more compact than conventional induction motors. IP54 rated, they are ideal for industrial applications that require protection against the entry of dust, the occasional water splash and exposure to other contaminants.

The very high torque-to-inertia ratio creates a high dynamic response and gives consistent and repeatable machine performance. A special feature is the patented MAX GUARD insulation system which combines corona resistant magnet wire and a low stress winding configuration to deliver long, dependable motor life.

The SyMAX FHP's neo rare earth magnets are fully encased and provide high energy efficiency. For ease of installation the FHP is designed as a drop-in replacement for equivalent induction motors. Other notable features include rolled-steel construction, constant torque or constant speed operation, a choice of integrated control, separate control and/or motor-only construction, 60Hz three-phase input, 5000 RPM output, options for feedback sensor, and UL and cUL approval.

This new product launch comes hot on the heels of the introduction of the Lesson EcoAg range of high efficiency motors, primarily for use in agriculture but also suitable for a wide variety of applications in remote or outdoor environments. The motors are available in single phase and three phase versions. The single phase design ranges from 0.3hp to 2hp with frame sizes from 56 to 145T. The three phase version goes up to 10hp and frame size 215T. All have an output speed of 1800rpm.

The energy efficiency of the EcoAg range is said to be up to 22% better than industry standards for agricultural motors, giving a substantial saving in annual power costs. Typical agricultural uses will include fans, augers, feeders, grain dryers, and processing equipment, while non-agricultural applications include a wide range of pumps and machinery for forestry, signage, aerials, access equipment, mobile handling and many other industries.
