Abstract

The present invention relates to a motor (1) and the control method thereof wherein the erroneous operation of the position sensors (4) can be detected without delay. The motor (1) of the present invention comprises a control unit (5) that gives an error signal and halts the operation when the output value of one position sensor (4) changes n times while the output values of the other position sensors (4) change less than (n-1) or more than (n+1).
