POWER TOOLS |
| 摘要 |
A power tool has a continuously variable transmission, a condition detection device, and an operation control device. The continuously variable transmission changes a velocity of a rotational output from a drive motor and outputs the rotational output to a spindle to which a tip end tool is mounted. The condition detection device detects a condition of the power tool. The operation control device determines a target RPM of the spindle based on the condition of the power tool detected by the condition detection device, and controls an RPM of the drive motor and/or a transmission gear ratio of the continuously variable transmission based on the target RPM. |

1. A power tool comprising:
a continuously variable transmission configured to change a velocity of a rotational output from a drive motor and to output the rotational output to a spindle to which a tip end tool is mounted; a condition detection device is configured to detect a condition of the power tool; and an operation control device configured to determine a target RPM of the spindle based on the condition of the power tool detected by the condition detection device, and to control an RPM of the drive motor and/or a transmission gear ratio of the continuously variable transmission based on the target RPM. |
