Features BLDC motor t-Rex 3200 I-44-89-L12 S2

14-pole BLDC motor with high-performance neodymium magnets and three digital Hall sensors for detecting the rotor position. The electrical connections are designed as a plug-in system. Additional power electronics are required to operate the motor. A motor version with hollow shaft is also available on request. This makes it possible to feed the cables through the motor or to realize a double-sided output.

Special features

  • Developed with focus on speed
  • Enormous power density - 3 times more powerful than motors of comparable size
  • High overload resistance
  • Best suited as direct drive or as 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.
