发明名称 SERVO MOTOR
摘要 PURPOSE:To position a pulse encoder accurately and easily by setting the groove made in the specified position of the rotary shaft of a motor, which generates pulse rows between which there is a phase difference of 90 deg., and an alignment mark, which is carved in the specified position of the casing of a motor, with each other. CONSTITUTION:A key groove 22 is carved in the specified position of the rotary shaft of a motor 1 which generates two systems of continuous pulses between which there is a phase difference of 90 deg.. Moreover, an alignment mark 21 is made in advance in the specified position of the casing of the motor mounted on a flange 12. When coupling the motor 1 with an encoder 2, the key groove 22 and the phase alignment mark 21 are set so that the signal of the specified position of the rotary shaft of the rotational position detector of an encoder 2 may be output in the specified position of the casing of a servo motor 1. Hereby, the pulse encoder 2 is set easily and accurately.
