Rotary-drive ammunition reloading systems with discontinuous stroke speed

An ammunition reloading system configured for attachment to an ammunition reloading press to automate the ammunition reloading press, the ammunition reloading system comprising:

• a motor;
• a power transmission assembly coupled to the motor and configured to couple to a drive component of an ammunition reloading press, the power transmission assembly being configured to enable rotational power in a single direction from the motor to drive the ammunition reloading press;
• one or more press position sensors configured to determine a position of the ammunition reloading press within a press stroke cycle;
• a controller communicatively coupled to the motor and to the one or more press position sensors, the controller being configured to:
• receive press position information from the one or more press position sensors,
• determine a position of the press within the press stroke cycle,
• in response to determining that the position of the press within the press stroke cycle corresponds to being at or near a top of the stroke, decrease a speed of the motor to a first speed,
• in response to determining that the position of the press within the press stroke cycle corresponds to being at or near a bottom of the stroke, decrease the speed of the motor to a second speed, and
• in response to determining that the position of the press within the press stroke cycle corresponds to a beginning of rotation of a case plate of the ammunition reloading press, decrease the speed of the motor to a third speed.
