Curtis Dynamometer Services

Stage 2: Performance Measurements (Torque-Speed Curves) ◀▶

Curtis uses the controller of customer’s choice for the application and provides a torque-speed curve at one current and voltage.

• Optionally, Curtis can take measurements at different currents and/or voltages. For example, this test could indicate how the same motor/controller combination performs with a 56V bus versus a 48V bus, or the effect of a higher current controller.

Stage 2 Includes:

• Stage 1 services.
• Torque-speed curves measured at the performance envelope given the voltage, max current, and maximum speed requested by the customer.
• Plots indicating motor torque, motor power, bus current, bus voltage, system efficiency, and motor current.

(The underlying data are provided to the customer in Excel and MATLAB format).
