EC 45 4-Pole, 300 Watt High Torque Brushless Motor Provides Without a Gearhead

⚠️ Editor's Note: This product has been discontinued. Newer models are available. This page is for reference only.

The Maxon EC 45 4-pole delivers the performance and lifetime of a brushless motor. A powerful 4-pole neodymium magnet provides high torque without a gearhead. The motors are electronically commutated, enabling extremely long motor life, since there are no mechanical brushes to wear out. By assembling the motor so that the coils are outside the rotor, good heat dissipation and high overload capability are attained. A high-resolution encoder that includes commutation signals is included.

The motor has a square cross-section of 45 mm (1.7 in) while the length is 155 mm (6.1 in), and it weighs in at 1,130 g (2.5 lb). Continuous output power is 300 W, and maximum speed is 10,000 rpm. Using a 4-pole rotor allows for an impressive maximum continuous torque of 515 mNm (73 oz-in). Ambient temperature range is -4O to 2,12O°F (-20O to 1,000°C). Using high-energy neodymium magnets results in an extremely responsive mechanical time constant of <2 ms, while minimizing overall size. Complementary control electronics are also available.

Due to their high torque capability and long lifetime, the EC 45 4-pole motors are well-suited for a variety of applications, including industrial automation, robotics, pick and place machines, and positioning applications.
