PROBLEM TO BE SOLVED: To prevent the leakage of lubricating oil from a bearing as a result of the reverse rotation of a motor during its stop in a controller for a one- directional rotation type motor having a grooved bearing to produce a dynamic pressure. SOLUTION: This controller has a configuration comprising conduction control means 7 for outputting a drive voltage of a motor 5, reverse rotation detecting means 9 for detecting the reverse rotation of the motor 5, and drive voltage adjust means 10 for adjusting the drive voltage output from the conduction control means 7 to the DC voltage 5; and the drive voltage adjust means 10 adjusts the drive voltage so as to prevent the reverse rotation when the reverse rotation detecting means 9 has detected the reverse rotation of the motor 5. |
