Overview
This document provides technical specifications and details for various t-Rex BLDC motor models, focusing on design, performance, and operational parameters. The motors are designed for high efficiency and performance, with customization options to meet specific operating points.
Specifications
  • Motor Models: t-Rex 3200 and t-Rex 3206, available in configurations focusing on speed or torque.
  • Rated Voltage: Options for 24 VDC, 36 VDC, and 48 VDC.
  • Rated Current and Torque: Varies by model, with currents from 4.0 A to 7.3 A and torques from 0.2 Nm to 1.9 Nm.
  • Efficiency: Maximum efficiency ranges from 74% to 84% depending on the model and configuration.
  • Motor Parameters: Includes terminal resistance, inductance, rotor inertia, and number of poles.
  • Interconnection: Motors are interconnected in a star configuration with two coils per phase.
  • Direction of Rotation: Bidirectional.
Procedures and Standards
  • Digital Hall Sensors: Used for rotor position detection, with a differential output conforming to RS422 standards.
  • Signal Structure: Hall sensors have a 120° phase shift, with signal frequency seven times higher than the speed due to the 14-pole design.
Design and Customization
  • Motors can be designed and manufactured to specified operating points, with special winding available upon request.
  • Options for hollow shaft design to allow cable routing through the motor.
Mechanical Details
  • Various mechanical dimensions and mounting options are provided, including pin strip configurations and feather key specifications.
