The Maxon EC 40 motor combines high power density, quiet running and hi stall torque.
Maxon announced its EC 40 motor, which features a neodymium permanent magnet, stainless steel housing and welded flanges. It also features a flat speed/torque gradient (about 3.6 rpm/mNm), mechanical time constant 2.1 ms, permissible speed 18,000 rpm, and efficiency of 89 percent. The ironless winding offers extra quiet running and high stall torque, the company says. As with all maxon motors, the EC 40 can be combined with a multitude of components, such as encoders or gears. As a new member, the permanent magnet brake AB 32 joins the maxon modular system. It is designed for operating temperatures of 40 to +100°C.
