PURPOSE:To obtain a motor speed controller which can prevent misdetection of speed data due to a delay of updating detection data of speed during low- speed rotation even by using a low-cost and small-sized encoder. CONSTITUTION:This controller has a cycle detection means 1 which measures a cycle of encoder signals by counting clock signals, an arithmetic device 2, a data holding means 3, and a correcting means 4. |
