Abstract
A synchronous reluctance motor, in particular a four-pole synchronous reluctance motor includes a stator with 48 stator grooves for receiving a winding system; a reluctance rotor, which is spaced apart from the stator by an air gap. The reluctance rotor has axes with a high magnetic conductivity (d-axis) and axes with low magnetic conductivity (q-axis). Provision is made for an arrangement of magnetically conductive flux-conducting portions and magnetic flux barriers, which are arranged such as to form the d-axis and the q-axis of the reluctance rotor. The reluctance rotor has a geometric groove separation angle of αr 6° or 10°, which angle is between two adjacent magnetic flux barriers at the air gap.
