In this paper, the object is estimation and torque control of the claw pole eddy current dynamometer. The eddy current dynamometer is included DC excitation coil, poles and rotational cylinder that coupled to the electrical motor. Load testing of electrical motor in different operating point is done through torque control of dynamometer. The close loop system of eddy current dynamometer has two inner and outer control loops. In outer control loop, the torque should estimate. The torque estimation is presented as a function of DC excitation current and rotational speed. After that, as regards to comparison of reference torque and estimation torque, the reference current is determined. Finally, the control of DC current source is done to generate the reference current. Both controllers of loops are PI controller. The experimental and simulation results for 22.5 KW eddy current load is shown the efficiency of proposed estimation and control method. The implementing system is done by using the ARM-LPC-1788 micro controller.
