PM Synchronous Motor | 255-AES48-070

Technical Data Sheet: 255-AES48-070

The 255-AES48-070 Permanent Magnet Synchronous Motor (PMSM) is a high-performance 3.5 kW 48VDC PM Synchronous motor, perfect for a variety of industrial and automotive applications. With over 90% efficiency, it ensures smooth, quiet, and energy-saving operation, making it an excellent choice for Electric and Hybrid vehicles, Agricultural equipment, Industrial Machinery, and more.

This motor stands out with its impressive capabilities, delivering a peak power of 14.4 kW and a rated torque of 7 Nm while reaching a peak torque of 33 Nm. With a rated speed of 4600 RPM, it offers the perfect balance of power and efficiency, ensuring smooth and reliable performance in even the most demanding applications.

Performance Curves

Robust Testing Process

To ensure its reliability and endurance, we subjected the 255-AE48-075 PMSM to rigorous testing. The motor was put through its paces with maximum current settings at 75 Arms, 115 Arms, 150 Arms and 225 Arms. Even under these demanding conditions, the motor exhibited resilience, with maximum temperatures reaching just 63 degrees, 85 degrees, 108 degrees and 125 degrees Celsius during one-hour continuous testing. 

While the maximum current ratings were established during testing, the motor doesn’t rely on the maximum root mean square (RMS) current throughout its entire RPM range. Instead, it adapts to deliver lower RMS currents at higher speeds, ensuring both efficiency and reduced energy consumption.
