SURFACE MOUNT PERMANENT MAGNET MOTORS

Reuland's Surface Mount Permanent Magnet (SPM) motors are designed to produce high peak torques at low speeds and are thus a perfect choice for high speed applications requiring high torque at low speeds. These motors are designed to be operated with an inverter, a closed-loop control, and resolver feedback. The stator on these motors consists of a conventional 3-phase winding while the rotor is made up of a small core with high energy magnets mounted on the exterior of the core.

Reuland's Surface Permanent Magnet motors are available in water-cooled enclosures and in power ranges of up to 500 HP.
