摘要:
The purpose of the invention is to provide a motor in which it is possible to efficiently construct a structure wherein a terminal part of a motor body is covered by a terminal cover. This terminal cover (7) is a resin molded article integrally including a first member (8) fixed to a motor body (40), a second member (9) that covers the first member (8), and a hinge part (70). Thus, the first member (8) and the second member (9) can be engaged with one another by first fixing the first member (8) to the motor body (40), and then rotating the second member (9) at the hinge part (70) and covering the first member (8) with the second member (9). Thus, the number of components can be reduced compared to cases where the first member (8) and the second member (9) are constructed as separate members, and the task of attaching the second member (9) to the first member (8) can be performed efficiently.

A terminal structure (9) for a motor-driven pump (1) to be disposed in a storage tank for a liquid such as liquefied ammonia or the like interconnects a motor-side terminal element (30) of a first conductor cable (29) for supplying an electric power to a motor (12) of the motor-driven pump and a power source-side terminal element (36) of a second conductor cable (35) for supplying the electric power from an electric power source. The terminal structure (9) has a hollow tubular housing (25) accommodating a conductor (41) and having upper and lower ends (37, 31) through which the power source-side and motor-side terminal elements (36, 30) extend into the housing and are electrically connected to the conductor (41) therein. The motor-side terminal element (30) is sealingly connected to the lower housing end (31) by a sealing mechanism (28, 28A) which utilizes sealing ring (33A, 33B; 133A, 133B) of a metal while the power source-side terminal element (36) is sealingly connected to the upper housing end (37) by a sealing mechanism (27) which utilizes gaskets (26A-26C).

A contact arrangement (7) for electrically contacting an inner and an outer bearing element (5a, 5b) of a rotational bearing (3) allowing a coaxial rotation between the inner and outer bearing elements (5a,5b) is provided. The contact arrangement (7) comprises - a contact holder (9) mountable on a first one of the two bearing elements (5a), - at least two sliding contact elements (11a,11b) mounted on the contact holder (9), wherein each sliding contact element (11a,11b) is suitable for forming a sliding contact with a part of a surface (13a,13b) of the second one of the two bearing elements (5b), wherein the contact holder (9) and the sliding contact elements (11a, 11b) are disposed such that a secondary winding (15) is formed with at least one winding loop (15) extending along a first sliding contact element (11a), the contact holder (9), the second contact element (11b) and a part of the surface (13c) of the second bearing element (5b), provided that the surface is formed of an electrically conductive material. The contact arrangement (7) further comprises a primary winding (17) with at least one winding loop (17i), wherein the primary (17) and secondary (15) windings are disposed to form a transformer. Furthermore, a rotational bearing with at least one such contact arrangement is provided, as well as a wind turbine with such a bearing and a method for operating such a rotational bearing.
