23 Claims

1. An electric motor, comprising:

a fan guard;

a rotor shaft mounted rotatably relative to the fan guard;

a torque support connected to the fan guard; and

an angle sensor including a housing connected to the torque support;

wherein the torque support has meandering and/or meander-like webs that repeatedly have an increasing and then decreasing circumferential angle as a radial distance from an axis of rotation of the rotor shaft increases;

wherein each web includes regions that are radially spaced apart from one another in a respective circumferential angle region and/or within the circumferential angle region covered by the web.
