This work aims to develop a new measurement method to monitor the speed, velocity, and mechanical impedance of a DC motor platform without using conventional sensors. A back-drivable DC motor platform is developed which uses the motor as sensor cum actuator. The sensor cum actuator determines the mechanical impedance of the moving load. By calibrating the Transduction Matrix of the DC motor the angular velocity and torque load of the motor can be measured via measuring the motor's electrical impedance. The method is validated by measuring mechanical impedance of an out center linear spring that generates dynamically changing impedance.
