The RE 50 motor is a high-density 200-W power pack, featuring an ironless rotor for detent-free running and minimized mass inertia.The combination of a two-pole neodymium permanent magnet with the company’s winding technology results in high torque and above-average acceleration. The drive measures Ø50 × 108 mm and is available with four different windings. Features include preloaded bearings, 0.38-Nm torque, speed of 2,800 to 5,700 rpm, 90% efficiency, low 24.70-Vdc voltage, and high-power density.maxon precision motors inc., 101 Waldron Rd., Fall River, MA 02720, (508) 677-0520, www.maxonmotorusa.com
