t-Rex 3200 (short version, focus rotational speed) I-44-47-L41 S2
3200.00-3000 with shaft
possible
Feather key DIN6885-A-4X4X12
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

Differential output
(RS422 standard, datasheet AM26 C31-TI) Typical voltage range: 0.2/ 3.4 V @ 20 mA Output current: max. 20 mA
Signal structure: The Hall sensors have a 120°
phase shift to each other
Due to the 14-pole design the
Signal frequency is seven times higher than the speed
