Permanent Magnet




  • Ultra-efficient design
  • High power density, low weight design
  • Designed with powerful rare earth magnets in rotor
  • Performance matched to PM drive
  • Compact, modular and lighter designs compared to AC induction motors
  • Wide speed range (up to 2000:1 constant torque)
  • Low operating temperature reduces maintenance
  • IP43 ingression protection (rolled steel frame)
  • IP54 ingress protection (cast iron frame)
  • 3-year warranty


  • Ultra efficient reduces energy consumption, offering utility savings
  • Desired output power in smaller frame sizes
  • Powerful magnets allow motor to operate at higher speed and give better performance
  • Maximum flexibility and easier drive selection with PM drives. Possible use of next lower drive size
  • Compact/lighter designs allows for reduction or elimination of mechanical PT equipment
  • Contributes to lower overall machine weight
    • Simplifies installation
    • Easy to retrofit
  • Optimal performance for constant torque loads
  • Minimized rotor loss to reduce operating temperatures which increases service life

Platinum e™ permanent magnet technology provides energy savings across a broad range of fractional and integral horsepower motors. By reducing rotor losses, the patent-pending radial magnet design improves motor efficiency as well as specific output power. The compact design of Platinum e™ motors enables easier integration into existing machine designs and processes to optimize system efficiency.


A Platinum e™ motor paired with a LEESON® VSD or VSD–Plus Series Variable Frequency Drive will help optimize your mechanical systems to achieve maximum output and reduce electrical energy consumption, all to minimize cost of operation.
