DR - Tricycle Test Machine

I. Main Function Description: 

This equipment is mainly used for testing electric motorcycles, bicycles, electric scooters and electric tricycles. The vehicle is fixed on the fixture, and the equipment supplies power to the vehicle's motor. The start-up of the vehicle is set to make it rotate. During operation, the load motor provides a programmable load torque to the wheels. The equipment detects the load torque, rotational speed, voltage and current of the vehicle during operation, calculates the load power and input power of the power supply, and plots curves. It can perform tests such as "maximum speed test", "road driving test", "acceleration performance test", "constant speed test on chassis dynamometer", "constant force test on chassis dynamometer", "constant speed climbing test", "maximum slope climbing test", "climbing test at a certain slope", "motor temperature rise test", "current on-off test", "100 km acceleration test", "maximum speed test", "high power test", "range test by working condition method and constant speed method", "under-voltage protection test", "100 km power consumption test", etc. on electric motorcycles. All test data are recorded and support the generation of reports and export.
