HT-250 Integrated Motor - Generator & Variable Frequency Drive TesterFeatures:

  • Simultaneous testing of integrated motor generators and variable frequency motor drives up to 25 kW or 90 Nm.
  • Reduced R&D cost by testing two components with only one machine.
  • Designed to deliver maximum capabilities, flexibility and accuracy optimized with extended measuring, documentation and statistical functions.
  • Measures Motoring - Generating: Active & Apparent Power, Power Factor, Efficiency, Torque, Resolver Angle, Back EMF, EMF Constant, Amplitude Imbalance, DUT Temperature and optional Sound and Vibration.
  • Automated endurance test with programmable scripting of test procedures.
  • Precise Performance via High Resolution data acquisition system.
  • Phase imbalance measurement technique able to detect and display phase imbalance conditions.
  • Expanded report statistical capabilities. User programmable report generator sends results to MS Excel® for performance report print out. Previous test can be retrieved for display.
  • Expandable measuring interface for custom requirements.
  • Temperature inputs and auxiliary analog channels available for customer defined measurements.
  • Water based coolant input - output or optional Oil circulation unit with constant flow and temperature.
  • Scalable measuring system can be configured with optional components for testing larger capacity devices.
