Abstract
A device for measuring torque on an electric motor, which has a first motor portion and a second motor portion, which are rotatable in relation to each other, is proposed, the device comprising a rotatable holding plate for receiving the first motor portion, by means of which plate a rotational movement of the first motor portion in relation to the second motor portion can be driven, and a holding device for the second motor portion for holding the second motor portion in a rotationally fixed manner, the holding plate being disposed and formed in such a way that, when external forces are exerted on the electric motor via the holding device, the electric motor can position itself in relation to the holding device in such a way that external forces influencing the torque measurement are minimized.
