A linear motor (30), including a mover and a stator, the mover having a cylindrical body (33) that forms an elongate circular bore (31) and the stator being an elongate shaft disposed within the bore. The cylindrical body (33) includes a plurality of electrical windings (32) and the shaft includes a synchronous or variable reluctance topology, or a plurality of magnets. Electrical energising of the windings (32) results in relative movement and/or force generation between the cylindrical body (33) and the shaft. The cylindrical body (33) being disposed within a housing (37) with a coolant space (35) being formed between the cylindrical body (33) and an internally facing cylindrical surface (38) of the housing (37). The coolant space (35) being formed along at least a major portion of the length of the cylindrical body (33) and the coolant space (3) being substantially cylindrical and of substantially constant cross-section.
A linear motor, including a mover and a stator, the mover having a cylindrical body that forms an elongate circular bore and the stator being an elongate shaft disposed within the bore, the cylindrical body including a plurality of electrical windings and the shaft including a synchronous or variable reluctance topology, or including a plurality of magnets, whereby electrical energising of the windings results in relative movement and/or force generation between the cylindrical body and the shaft, the cylindrical body being disposed within a housing with a coolant space being formed between the cylindrical body and an internally facing cylindrical surface of the housing, the coolant space being formed along at least a major portion of the length of the cylindrical body, the coolant space being substantially cylindrical and of substantially constant cross-section.
A linear motor, including a cylindrical body that forms an elongate circular bore and an elongate shaft disposed within the bore, the cylindrical body including a plurality of electrical windings and the shaft including a plurality of magnets, whereby electrical energising of the windings results in relative movement between the cylindrical body and the shaft, the cylindrical body being disposed within a housing that has opposite first and second ends, whereby the cylindrical body includes a flange for attachment to one of the first and second ends for mounting the cylindrical body within the housing.
