摘要： A synchronous motor comprises a stator (41) provided with a number of armature windings corresponding to the number of phases o/ of a power source, and S slots (42) housing the armature windings; and a rotor (31) provided with the same number of field poles (32) as poles P of the rotor (31), and magnets (33) for exciting the field poles (32). When the number of slots per pole and phase, S/Po/, is expressed by an irreducible fraction m/n, the circumferential length (W) of the part of each of the field poles (32) facing the slots (42) of the stator (41) is selected to be an integral multiple of 1/n of the pitch (L) of the slots (42) of the stator (41), to reduce the amount of slot ripple and speed irregularities when the motor is lightly loaded when used as a servo motor.

摘要： A method of removing follow-up delay using a digital servo system in a full-close feedback NC system, in which a position instruction is received from an NC controller (11), and in which a speed instruction (12) and a torque instruction (13) are supplied, in order to drive a table of a machine tool via a servo motor (14). A position detection value is produced from the servo motor. Further, a step (18) is provided wherein a correction instruction (19) having a correction quantity (K. DELTA X) and a correction time (1:Pg:K) ( DELTA X denotes a play of the table, Pg denotes a position gain of the servo system, and K denotes a correction coefficient) is added to the position instruction (11) at a moment when the moving direction of the table is reversed so that the position error becomes zero, and wherein the addition is stopped at a moment when a position detection value of the servo motor becomes equal to a position detection value of the table. Thus, a machine tool which produces little error in position can be obtained.

摘要： A rotor (10) is divided into 2n rotor elements (101, 102, 103, 104) to eliminate n kinds or the component (A, B) of the torque ripple of a synchronous motor. In order to eliminate the first component (A) of the torque ripple, the two rotor elements of each of 2n-1 rotor element pairs (101, 102; 103, 104) are shifted from each other by an angle corresponding to the half of the wavelength (μ) of the first component. In order to eliminate the second component (B), the 2n-1 rotor element pairs are divided into 2n-2 rotor element groups, each of which comprises the two pairs that are shifted from each other by an angle corresponding to the half of the wavelength (η) of the second component. The shifting is repeated until the n-th torque ripple component is eliminated, thus constructing a rotor.

摘要： In order to fix a pulse encoder to a motor, a stationary code plate (20) is attached temporarily to an end portion (18) of a motor housing (12), and the motor housing (12) is then turned around a motor shaft (14) so as to correct the eccentricity of the stationary code plate (20). A gauge (50) is inserted between the stationary code plate (20) and a rotary code plate (48) to space the rotary code plate (48) from the stationary code plate (20) by a predetermined distance. The motor shaft (14) is then turned with respect to the motor housing (12) so as to correct the eccentricity of the rotary code plate (48) which is attached temporarily to a sleeve (42). If this method is employed, the pulse encoder can be fixed to the motor accurately and efficiently.
