Abstract

A disc resolver of an electric motor, especially of a brushless direct current electric motor, has at least one rotating disc (3), (resolver rotor) and one stationary disc (4), (resolver stator). The two discs are arranged essentially in parallel with respect to each other and distanced from each other by an axial gap (5), wherein the resolver stator has at least one first stator winding (6) at a first stator front side (7) and the resolver rotor (3) has at least one rotor winding (8) at a rotor front side (9) facing the gap (5). The rotor winding runs according to the arrangement and number of motor poles, especially half poles of an electric motor (2). Thereby, a disc resolver of an electric motor is provided, which, under simple construction and cost-efficient manufacturing, enables very precise position evaluation in quite different rotational speed ranges and, especially under creep speed, also under high pressure.
