Permanent-magnet Axial (PA) Series PM Motors and Generators

PA44

Deliver more power per pound with continuous high torque, even at a stall.

Lightweight and compact, the Permanent-magnet Axial (PA) was built to last under the world’s most demanding applications. And since the PA rotor uses permanent magnets, it works equally well as a generator, making it the ideal choice for mobile generator sets, traction systems, cranes, elevators and lifts.

The PA series is ideal for applications requiring high precision and/or high torque, at a low weight and small size.

 

PA44-625 Permanent Magnet Motor

Proven by years of reliable performance in harsh, rugged applications, the Leonardo DRS PA44-625 permanent magnet motor producing 625 HP (466kW) and at only 395 lbs., is one of the most power dense motors available in industry today.  For higher power needs the PA44-625 can be coupled to achieve 1,250 HP (932kW) of power. 

 

PA57

PA57-1000 Permanent Magnet Motor

Rated at 1,000 HP (750kW), the Leonardo DRS PA57-625 permanent magnet motor with years of service in transit hybrid electric propulsion, is ideal for hybrid electric and propulsion systems for all applications up to 2,000 HP (1.5MW) with two motors coupled together.  

 

PA Series Drive Options

With a long history of robust Variable Frequency Drives, Leonardo DRS offers several options to support all your power conversion requirements for the PA series motors and generators.  The MD500A VFD is a significant upgrade of the MD500 VFD that has been coupled with the PA44 for over 20 years in Oil and Gas applications.  The Silicon Carbide PEM drives offer compact size using the latest in VFD technologies configured to drive both the PA44- 625 and the PA57-1000 to solve all your propulsion and power needs.
