Abstract
Lathe control systems and methods are described including stopping a motor prior to reversing direction as well as methods and systems that implement voltage and/or current protection thresholds.
Claims15
A lathe comprising:
- an electrical motor drivingly coupled to a shaft of the lathe;
- and
- a controller that controls a power applied to the electrical motor during operation, wherein when an operating direction of the electrical motor is reversed from a first direction to a second direction, the controller powers off the electrical motor until the electrical motor stops rotating and then the controller applies power to the electrical motor to drive the electrical motor in the second direction.
A method comprising:
- detecting a signal to reverse an operating direction of an electrical motor drivingly coupled to a shaft of the lathe from a first direction to a second direction;
- powering off the electrical motor until the electrical motor stops rotating;
- and
- applying power to the electrical motor to drive the electrical motor in the second direction.

A method comprising:
- detecting an electrical characteristic of at least one of an electrical bus and an electrical motor of a lathe;
- and
- controlling at least one aspect of the electrical motor's operation based on a comparison of the detected electrical characteristic to a preset threshold.
