  System customization selection reference:

  The following table is a reference for the selection of a customized dynamometer loading system. Customers can configure their dynamometers and other hardware according to the test requirements and specific performance parameters of different motors. No sensor on the market can meet 0.1N·m and 1000N at the same time. · Two ranges of m. Example: The torque application range of our company's AHD-103 (rated torque 1N·m) hysteresis dynamometer is recommended in the range of 0.1N·m-1N·m.
