Abstract
Disclosed are systems and methods for protecting an escrow clutch of a self-service terminal. The systems and methods may include actuating a motor of the self-service terminal to cause an escrow clutch of the self-service terminal to spin at a rate. As the clutch spins, a determination as to when a clutch slippage exceeds a preset slippage rate may be made. When the clutch slippage exceeds the preset slippage rate, the motor may be actuated to cause the escrow clutch to spin at a second rate. The second rate may less than the first rate.
Claims20
A method, comprising:
- determining a slippage an escrow clutch of a terminal during a transaction at the terminal;
- determining a current temperature of the escrow clutch exceeds a preset temperature based on a current torque calculated for the escrow clutch;
- and
- actuating a motor causing the escrow clutch to spin at a lower rate from a current rate based on determining the slippage and determining the current temperature exceeds the present temperature.
A method, comprising:
- monitoring a current draw of an escrow clutch for an escrow of a terminal during a deposit of notes;
- determining a current torque of the escrow clutch based on the current draw;
- determining a current temperature of the escrow clutch based on the current torque;
- determining a slippage of the escrow clutch based on the current draw, the current torque, and the current temperature;
- and
- controlling a current voltage for a motor of the escrow clutch causing the escrow clutch to spin at a lower rate than a current rate based on the slippage.
A clutch controller, comprising:
- a processor of a terminal;
- and
- a non-transitory computer-readable storage medium comprising executable instructions, that when executed by the processor cause the processor to perform operations, comprising:
- determining a current draw by a motor of an escrow clutch for a note escrow of a terminal;
- determining a current torque of the escrow clutch from the current draw;
- determining a current temperature of the escrow clutch from the current torque;
- determining a slippage of the escrow clutch based on the current draw, the current torque, and the current temperature;
- and
- controlling a current voltage of the motor causing the escrow clutch to spin at a lower rate than a current rate when the slippage exceeds a preset clutch slippage.
