Ứng dụng cảm biến Momen Xoắn trong xe chạy năng lượng mặt trời (Stanford Solar Car Dyno)

Stanford’s 2013 Solar Car Project team utilized Lorenz’s Shaft to Shaft Rotary Torque Sensor to emulate what the motor will be subjected to on race day through a dynamometer.

How it Works
  1. The Stanford Solar Car Project team wanted to add a clever twist to their dynamometer (dyno): implement one of Xenith’s regenerative brakes as its energy absorber.
  2. This setup would allow them to simultaneously study the efficiency of their regenerative braking system while testing their motor.
  3. To gain perspective on if this approach could be realized, the SSCP Team called on the experts at Lorenz.
  4. Consulting led to a clear direction that their dyno would need a Rotary Torque Sensor at the center of its measurement system. (As seen here: Stanford custom motor)
  5. The DR Series sensor integrates a rotary encoder with a freely spinning torque transducer.
  6. The DR could then be situated directly between the motor’s crankshaft and the regenerative brake allowing the both torque and displacement measurements to be simultaneously captured by a single sensor.
  7. The USB Lorenz LCV-USB3 is the ideal data exchange solution for systems that require translation of rotary torque encoder readings, such as angle and speed. Its compact and robust design also makes the LCV-USB3 fitting for this type of application.
