    摘要： The invention relates to an electric motor (10) comprising an electromotive brake, in particular for angle grinders, a stator (12) which has at least one pair of poles (16, 18), at least two poles (16, 18), each having a pole shoe (17, 19) which is oriented inward toward a rotor (14) and surrounded by a winding (24). The stator (12) receives at least one braking device (26) for decelerating the rotor (14), said device comprising a braking element (28), wherein the braking element (28) can be moved against the outer circumference of the rotor (14) for the purpose of braking and can be moved counter to the braking force by the magnetic field when the electric motor (10) is energized. According to the invention, the braking device (26) is arranged in the stator (12) in the circumferential direction between the two poles (16, 18) and the braking element (28) is designed as a single-armed brake lever (29) which, at one end thereof, can be pivoted about a pivot point (30) in the stator (12), so that mounting the brake lever (29) by means of a shaft or axle is dispensed with.
