摘要： An AC spindle motor (10) used for driving the spindle of a machine tool has a rotor (14) with an output shaft (12) that can be coupled to the spindle, and a stator (16) arranged to surround the rotor (14), the stator (16) having a laminated core (20) that forms a yoke and three-phase (U, V, W) stator windings accommodated in the winding grooves (22) of the laminated core (20) to form a revolving magnetic field. The windings (18u, 18v, 18w) of three-phase stator windings for forming the revolving magnetic field have: a first set of windings (C2, C4) served with a drive current in either a low-speed region where the revolving speed is smaller than a predetermined value and a high-speed region where the revolving speed is larger than the predetermined value; a second set of windings (C1, C3 served with a drive current in the low-speed region only; and electric contact means (S1 to S4 which so switch the circuit that the drive current is supplied to the first and second sets of windings (C2, C4, C1, C3) simultaneously during the low-speed operation to form a first plural-pole revolving magnetic field and that the drive current is supplied to the first set of windings (C2, C4) only during the high-speed operation to form a second plural-pole revolving magnetic field, the number of the second plural poles being smaller than the number of the first plural poles. The ampers turns of the windings and the number of poles are changed depending upon the low-speed operation and the high-speed operation.

摘要： The working operations in a machine tool include the case where a high output at a low speed rotation is required and the case where the high output at a high speed rotation is required. To carry out these operations by one motor, each phase coil winding (X1, X2; X1', X2') is divided into a plurality of sets and a plurality of sets are inserted through each slot (SL). The terminals (U1, U2; V1, V2; W1, W2) of each phase as their division points are switched by switch means (SW, SW') such as electromagnetic relays so that the coil winding for supplying the power is selected and the ouput can be adjusted.

摘要： For a recent motor requiring larger output and torque, liquid-cooling is preferable for increasing cooling efficiency and, because of simplicity of construction, the so-called jacket system is employed for cooling the stator (17). The conventional jacket system, however, lowers cooling efficiency on account of a cylinder member interposed between the stator (17) and the jacket (18). In this invention, therefore, an adhesive is applied to the entire surface or a partial annular surface area (Z1) of each of laminations (16) composing the stator (17) and, with the laminations assembled, cooling liquid is prevented from entering the inner periphery of the stator (17) and thus a liquid passage (24) of the jacket (18) can be adapted to directly face the outer periphery of the stator (17).

摘要： The stator of a built-in motor must be correctly secured to the spindle head housing of a machine tool. For this purpose, the periphery of a stator core (10) which is a main portion of the stator is partly welded and is held by a mandrel or the like from the inside to grind the outer circumference (14) maintaining precision. After the mandrel and the like are removed, however, the stator core (10) may undergo deformation with the passage of time. To prevent this, a thermosetting adhesive is applied to the surface of the constituent element plates (12) of the stator core (10) to bond them together, or the constituent element plates (12) are provided with a protuberance (22) as the outer circumference (14) is welded to bond them together, or a serration bar (26) is forcibly inserted in a hole (24) of the element plates (12) instead of providing the protuberance (22) to bond them together.

The motor is further provided with terminals Z, X and Y connected with its terminals U, V and W through switches (37). When the switches (37) are closed and the switches (35) are set to interconnect the terminals Z, X and Y, the winding of the motor becomes Y-connection and the motor is directly connected to the power source. On the other hand, when the switches (37) are opened and the switches (35) are set to connect the terminals Z, X and Y to the terminals U, V and W, the winding of the motor becomes delta-connection and the motor is connected to the power source through the reactor (32).

摘要： When a main spindle (10) is rotated and the main spindle and a work are moved linearly and relative to each other in the axial direction (Z) of the main spindle in, for example, the threading of a machine tool, a spindle servo-motor (12) and a feed servo-motor (22) as the driving sources must be actuated while they are being synchronized. Generally, the spindle servo-motor drives directly the main spindle without resort to a reduction gear but the feed servo-motor drives a main spindle head (18) through reduction gears (26, 28). Therefore, the synchronization is generally governed by the acceleration/deceleration performance of the spindle servo-motor. The synchronization with maximum efficiency can be accomplished by accelerating and decelerating the main spindle while actuating the spindle servo-motor in line with its torque limit curves (L1, L2).
