<p>PROBLEM TO BE SOLVED: To provide a rotation angle detector that can be used while being provided in parallel to a resolver circuit.SOLUTION: In a rotation angle detector 1, a sample pulse generator 15 outputs a sample pulse signal having a predetermined pulse width on the basis of a peak pulse signal output from a peak detection unit 14. A sample and hold unit 16 receives a rotation angle signal containing rotation angle information on a motor 10 output from a resolver 11 and holds a voltage of the rotation angle signal on the basis of the sample pulse signal. An arithmetic unit 17 acquires the voltage held by the sample and hold unit 16 and calculates a rotation angleθof the motor on the basis of the voltage.</p> |
