Abstract
This invention discloses an electric motor comprising a stator, a rotor disposed concentrically within the stator, a drive shaft rotatably supporting the rotor with a circular gap between the stator and rotor and an output shaft connected to the drive shaft and sharing the same rotating axis with the drive shaft, wherein the improvement is characterized in that the electric motor further includes a resilient connecting member which connects the drive shaft and the output shaft and means which detects the torsion of the resilient connecting member produced during the transmission of the torque from the rotor to the output shaft and measures the transmission torque from the detected torsion.
