摘要： The present invention relates to an actuator for a medium voltage circuit breaker. The actuator comprises a rotor, a stator, and at least one coil. The rotor is configured to be fixedly mounted to a main shaft of a circuit breaker of a medium voltage switchgear such that the rotor and main shaft rotate together. The stator is configured to be mounted at least partially around the rotor. The at least one coil is wound around at least a part of the stator. An angle of rotation of the rotor with respect to the stator is limited.

摘要： The present invention relates to an actuator (1) for a medium voltage circuit breaker. The actuator comprises at least one rotor (10, 80), at least one stator (40, 90), and at least one coil (70, 100). Each stator of the at least one stator is associated with a corresponding rotor of the at least one rotor. Each stator does not circumferentially completely encircle the rotor with which it is associated. Each coil of the at least one coil is associated with a stator of the at least one stator. Each coil is wound around at least a part of the stator with which it is associated.
