Abstract

PURPOSE:To reduce the capacity of a backup battery by dividing a plurality of MR elements disposed on a single carrier into a plurality of groups, and individually providing current supply terminals of the MR elements of the respective groups. CONSTITUTION:In a magnetic sensor which is mounted on a magnetic encoder used by directly couping it to a brushless motor in which a plurality of magnetoresistance effect elements (MR elements) are disposed on a single carrier, the plurality of MR elements are divided into a plurality of groups, and current supply terminals of the MR elements of the respective groups are individually provided. For example, a sensor which is required to be backup. The current supply terminals of the MR elements 5-1 and 5-2 are provided together to the terminal 5-6 through connecting conductors, and a backup power source is connected to the terminal 5-6. Further, when a servo system is stopped, it is not necessary to supply a current to the sensor, and the back with the battery is not necessary. The terminals of the MR elements 5-3, 5-4, 5-5 are provided together to the terminal 5-7 through other connecting conductors.
