CONTROL CIRCUIT FOR RECIPROCATING SAWS |
摘要 |
A reciprocating saw with a control system, which includes a rotational rate sensor having a resonating mass and a controller electrically connected to the rotational rate sensor. The rotational rate sensor detects angular or lateral displacement of the resonating mass and generates a signal indicative of the detected angular or lateral displacement, such that angular or lateral displacement is directly proportional to a rotational speed at which the power tool rotates about an axis. Based on the generated signal, the controller initiates a protective operation to avoid undesirable rotation of the power tool. |
