Motor Testing in Temperature and Humidity Environment

Dynamometer for Environmental Testers

Example of the Dynamometer system for the Environmental Tester
The HB-NT Dynamometer and the MMJ-TC01 Motor Mounting Jig (common use with all the Dynamometer models)
The MMJ-TC01 Motor Mounting Jig <br />(inside the chamber)<br />　　

The base of the HB-NT series Dynamometers for Environmental Testers is so designed that it is connected to the side of the base of the Environmental Tester (temperature & humidity chamber). The Brake Unit of the Dynamometer slides forward, inserting the sample motor with the dedicated MMJ-TC01 Motor Mounting Jig for the Temperature Chamber into a chamber.
This Dynamometer measures the rotation speed and torque of the motors under test at certain temperatures and humidity levels (e.g., from -40°C to 150°C) displaying the measurement results on a Windows PC. When combined with the Precision Power Analyzer, this model accurately and easily measures the input and output power of a motor with a high-frequency PWM controlled inverter.

Features of the Measuring Units

  • A total of seven different models are available (maximum torque 50 mN·m to 5 N·m).
  • All the seven models have the same dimensions, so that one set of the MMJ-TC01 Motor Mounting Jig can be used with the seven models in common.
  • The adjuster provided allows use with our MMJ series standard Motor Mounting Jig sets when you test the motor outside the temperature chamber.
  • Hysteresis brake control and torque detection using tension-bar type strain gauge load cell ensures stable measurements across a wide range of rotation speeds.
  • The MMJ-TC01 Motor Mounting Jig attaches directly to the reference plate of the Dynamometer for precise axial alignment with the sample motor shaft and for accurate measurements.
  • The standard chamber mounting base (provided) allows easy setup with the Espec Temperature (& Humidity) Chamber model SH/SU-642.
