Abstract

A motor controller includes an actuator and a programmable wheel. The actuator includes first and second conductive rods configured to receive external electric power. Each rod has upper and lower rod contacts. First and second crisscrossed electrodes are movable between, and electrically connectible to, the upper and lower rod contacts. A power terminal is electrically connected to the crisscrossed electrodes. The programmable wheel has first and second directional appendages mounted thereon. The wheel is configured to engage the actuator such that for each revolution of the wheel: the first directional appendage moves the crisscrossed electrodes into electrical contact with the upper rod contacts to route the electric power to the power terminal at a first polarity, and the second directional appendage moves the crisscrossed electrodes into electrical contact with the lower rod contacts to route the electrical power to the power terminal at a second opposing polarity.

Dependent claims

A motor controller, comprising:

an actuator, comprising:
first and second conductive rods configured to receive external electric power, each rod having upper and lower rod contacts,
first and second crisscrossed electrodes movable between, and electrically connectible to, the upper and lower rod contacts, and
a power terminal electrically connected to the crisscrossed electrodes;
and
a programmable wheel mounted on a motorized shaft, the wheel having first and second directional appendages mounted thereon, the wheel configured to engage the actuator such that for each revolution of the wheel:
the first directional appendage moves the crisscrossed electrodes into electrical contact with the upper rod contacts to route the electric power to the power terminal at a first polarity, the electric power at the first polarity operable to turn an electric motor electrically connected thereto in a first direction, and
the second directional appendage moves the crisscrossed electrodes into electrical contact with the lower rod contacts to route the electrical power to the power terminal at a second opposing polarity, the electric power at the second polarity operable to turn the electrically connected electric motor in a second opposite direction.

5 more elements

A motor controller, comprising:

a programmable wheel mounted on a motorized shaft, the wheel having first and second speed appendages mounted thereon;
a speed control switch electrically connected to an electric motor, the speed control switch comprising a switching mechanism having a first switch position and a second switch position, wherein, when the switching mechanism is in the first switch position, the electric motor rotates at a first speed, and when the switching mechanism is in the second switch position, the electric motor rotates at a different second speed;
and
a speed trigger mechanism, comprising a speed trigger rod configured to engage with the switching mechanism of the speed control switch, the speed trigger mechanism configured to move the speed trigger rod between an extended position and a retracted position;
wherein, for each revolution of the programmable wheel:
the first speed appendage engages the speed trigger mechanism to move the speed trigger rod into its extended position, thereby moving the switching mechanism of the speed control switch to its first switch position to operate the electric motor at the first speed, and
the second speed appendage engages the speed trigger mechanism to move the speed trigger rod into its retracted position, thereby moving the switching mechanism of the speed control switch to its second switch position to operate the electric motor at the second speed.
