Abstract

The invention relates to abasic body (1) for an electric motor (2), which comprises the following features: a substantially cylindrical outer wall (3), which forms a rotor space (4) for receiving a rotor (5) at least partially inside the outer wall (3) and on which a winding (6) can be mounted at least partially outside the latter; a laminated core (7) which is held by the outer wall (3); a receiving space (9) which serves to receive a printed circuit board (12) or another component of the electric motor (2) and which adjoins the rotor space (4); a partition wall (10) separating the receiving space (9) from the rotor space (4); at least one orienting device (13) for positionally orienting the printed circuit board (12) or the other component of the electric motor (2) inside the receiving space (9); a receptacle (17) for a cover (18) which closes the rotor space (4), said receptacle being situated on the outer wall (3) on the side of the rotor space (44) opposite to the partition wall (10); and an inner wall (20), which adjoins the partition wall (10), for receiving a bearing (21) for the rotor (5), said inner wall, together with the outer wall (3), creating the receiving space (9).
