        Features: 
          1. By digital PID adjustment, system can run constant   load(torque, current or powerin), and once the load be set, it will be   automatically stable in 2~3seconds without any outside adjusting by hand.  
          2.   Stable strips left-up loading(Multi-point value load), the number of point can   be over 10, with loading control of the constant current, torque and constant   input power. 
          3. Automatically do pwheel motor performance test   in 0~60 sec, and draw out the motor characteristic curve M=f(U, I, W, n,   P,η). 
          4. Do the test automatically or by hand, automatically save record   during test, and data print.  
          5. Using DC regulated Power supply with voltage   feedback, the motor's running voltage can not drop.  
          6. After 30~40mins   constant load(set by user), user can do temperature-rise test by AGR4 Resistance   Test Equipment, and automatically get the result by corresponding sofware.
