Motor run timer
First Claim
Patent Images
1. A motor run-time totalizer, responsive to the rotation of an associated motor, having a rotor, to indicate the amount of time the rotor has been rotating, the apparatus comprising:
- a) a housing arranged for attachment to the rotor b) a timer, in said housing, that will indicate the total accumulated run time that occurs while it is turned on;
c) a sensor means, in said housing, to sense the rotation of the rotor and to turn the timer on when the motor is running and turn it off when the motor is not running said sensor is a pendulum free to rotate about the axis of the rotor, the rotation of the pendulum relative to the rotor axis being sensed to start and stop said timer.

Abstract
A timer is enclosed in a pressure tight enclosure which is attached to or is part of the motor rotor. Rotation of the rotor is sensed and the timer is turned on when the rotor is turning and is turned off when the rotor is idle. The version usable in motors of the progressing cavity type can power the timer, and provide timer control.
