Features BLDC motor t-Rex 3200 I-44-47-L41 S2

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

Digital Hall-sensors

Supply of sensors
Voltage range: 4.5 to 5.5 V DC
Optional: voltage regulator for 5 V
Input current: < 70 mA

Output signals of sensors
Diff erential 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.
