Quality Motors by LEESON® Canada

When it comes to electric motors, LEESON® is synonymous with quality and energy efficiency. At Magneto Electric, we carry an extensive line of AC and DC LEESON® motors in Mississauga. Known for innovative thinking and viable designs, LEESON® is a leading small motor manufacturer. Whether you need an agricultural motor designed for tough conditions or an explosion proof motor suited for hazardous environments, LEESON® has reliable options available. 


This sought-after brand also produces pump motors designed for various applications. If you are looking for 1-Phase or 3-Phase AC motors, or a dependable DC motor, LEESON® is a name you can trust.

AC & DC Motors
While AC and DC motors both convert electrical energy into mechanical energy, they are powered, built and controlled differently. An AC motor typically consists of an outside stationary stator with coils supplied with an alternating current to produce a rotating magnetic field and an inside rotor attached to the output shaft producing a second rotating magnetic field. A DC motor is classified as any electrical machines that covert direct current electrical power into mechanical power, commonly relying on the forces produced by magnetic fields. Both types of motors are used for a myriad of different purposes and in nearly every industry imaginable.

LEESON® NEMA Premium® Motors
If you need reliable performance in heavy-duty industrial applications, nothing beats the LEESON® Heavyweights, 150 and 170 series. These cast iron motors have a service factor of 1.15, which makes them ideal for tough applications. When you choose the 150 or 170 series motors you’re getting a versatile unit that can be quickly field converted to a number of different configurations.

Protect Your Motor from Voltage Spikes
The LEESON® Inverter Rated Insulation System (IRIS™) provides superior protection against voltage spikes in your motor that can be induced by variable frequency drives. This total insulation system protects your unit better than spike-resistant magnet wires can on their own. Specially formed phase insulation, cushioned and sleeved connections from the leads into the tums, and deep-penetrating, non-hygroscopic, high temperature varnish are just a few features contributing to this extra protection. The IRIS™ offers all of these features plus second generation, spike-resistant magnet wire. The IRIS™ total insulation system is standard at no extra cost in all LEESON® stock NEMA® three-phase motors 1 HP and larger.
