t-Rex 3200 I-44-47-L21 S2 (short version, focus rotational speed)

Description

14-pole BLDC motor with high-performance neodymium magnets and three digital Hall sensors to detect the rotor position. The electrical connections are designed as a plug-in system. Additional power electronics are required to operate the motor. Motor design with a hollow shaft is also available upon request. This allows the cables to run through the motor or the implementation of output on both sides.

Special features

  • Designed with focus on rotational speed
  • Enormous performance density – 3 times stronger than motors of comparable size
  • High overload resistance
  • Ideally suited as direct drive, or generator for gearless applications
  • Special winding upon request
  • Design and manufacture of motor to specified operating point is possible
