Permanent Magnet AC Motors (PMAC Motors): Energy-efficient and versatile solutions for Industrial & Commercial applications
Our SyncMAX® brand features Permanent Magnet AC Motors (PMAC motors), marking a significant leap in motor technology with unmatched efficiency, durability, and versatility. By integrating robust permanent magnets in place of traditional rotor windings and brushes, PMAC motors outperform conventional induction motors. Grasping their unique advantages and diverse industrial and commercial applications can empower businesses to make informed choices about energy-efficient motor solutions.
What Are Permanent Magnet AC Motors?
Permanent Magnet AC Motors are electric motors that use powerful permanent magnets in the rotor, eliminating external excitation. This innovative design results in motors that are smaller, lighter, and more efficient than their induction motor counterparts. By reducing friction, heat, and energy loss, PMAC motors are one of the most energy-efficient motor types available today.

Key Benefits of SyncMAX Motors
Superior Motor Longevity
The use of permanent magnets minimizes internal friction, drastically reducing heat generation. This design protects critical components from insulation erosion and wear, translating to extended motor life. Industries relying on long-term, reliable motor performance can significantly benefit from this feature.
Advanced Speed Control
Speed control is a hallmark feature of PMAC motors. Unlike conventional induction motors, PMAC motors maintain high torque even at low speeds—eliminating the need for gearboxes in many applications. Their precise and smooth operation makes them ideal for industries requiring accurate control, such as robotics, manufacturing, and conveyor systems.
Unmatched Energy Efficiency
Energy efficiency is a top priority for modern businesses, and PMAC motors excel in this regard. They consume less input power to produce the same output, resulting in lower energy costs. Over time, this efficiency contributes to significant operational savings and a reduced carbon footprint, making them a sustainable choice for diverse industries.
- Ultra Efficiency power density, more HP rating per frame:
- Example: with an "Ultra Efficient" PMAC motor you can fit 20 HP in an 1800 RPM 215T frame versus a NEMA Premium AC Induction motor which fits 10 HP in an1800 RPM, 215T frame
- Over 40% reduction in motor energy losses compared to AC induction motors.
- Quick return on investment—typically achieved in under 18 months, allowing businesses to recover costs swiftly and start reaping the benefits of their investment in a short period of time.
