Electronic clutch for tool chuck with power take off and dead spindle features

A power driver comprising:

• a motor that receives an input current to drive a tool chuck supporting chuck jaws;
• and
• a control circuit to selectively interrupt the input current to the motor, the control circuit to receive
• a current value input indicating the input current to the motor, and
• a mode input indicating whether the power driver is set to operate in CHUCK MODE in which the motor rotates to one of open and close the chuck jaws;
• wherein the control circuit interrupts the input current to the motor if the mode input indicates that the power driver is set to operate in the CHUCK MODE and if the current value input exceeds a trip value.

An electronic clutch for a power driver having a motor that receives an input current to drive a tool chuck supporting chuck jaws, the electronic clutch comprising:

• a control circuit to receive
• a first input indicative of a clamping force applied by the chuck jaws, and
• a second input to indicate whether the power driver is set to operate in a CHUCK MODE in which the motor rotates to one of open and close the chuck jaws;
• the control circuit interrupting the input current to the motor if the second input indicates that the power driver is set to operate in the CHUCK MODE and if the first input exceeds a trip value.
