摘要： A cable clamp for clamping a motor cable includes a fixing member having a pair of bottom plates. The bottom plates are placed in parallel to each other to thereby define an opening. A pair of guide members are also placed in parallel to each other and bridge the bottom plates to further limit the opening. The motor cable is then received through the opening. A slide member slides along the pair of guide members to thereby clamp the cable. The bottom plates may optionally include a depression near the opening which defines a recess. A waterproof adhesive may be disposed within the recess to thereby form a watertight barrier.

摘要： An insulating member (10), which is disposed in each of slots (20) in a stator core (16) of a motor in order to insulate electrically the core (16) and windings (22) set in the slots (20), comprises a main insulating section 30, which covers the inner wall surface of the slot (20), and auxiliary insulating sections (32) having desired flexibility and flexural repulsiveness to substantially close and opening (26) of the slot. The auxiliary insulating sections (32) are easily deformed to allow the slot opening (26) to open partially when it is subjected to an external force, and are restored to their original state such that the opening (26) is closed when the external force is removed.

摘要： A method of expanding types of synchronous motors capable of reducing the number of required stator types to use stators in common, and a synchronous motor produced by the method. A group of stators are prepared by stacking stator cores of identical shape so that heights of the stators are different from one another to be multiples of a fundamental height. A plurality of groups of rotors are prepared so that lengths of the rotors in each group are different from one another to be multiples of a fundamental length. The rotors in each group are provided with permanent magnets having a residual magnetic flux density different from that of the permanent magnets for the rotors in the other groups. A stator and a rotor corresponding to a preset output torque specification value and a preset rotor inertia specification value are respectively selected from the group of stators and the rotor groups and are combined with each other, whereby an expanded type of motor is obtained.
