Abstract

A mailing machine base adapted to have a postage meter mounted thereon, wherein the meter includes a postage printing drum having a home position, the base comprising, structure for moving the drum, a d.c. motor for driving the drum moving structure, a microprocessor, a power switch connected between the d.c. motor and microprocessor, a comparator connected between the microprocessor and d.c.
motor for receiving therefrom a signal corresponding to the back e.m.f. voltage of the d.c. motor and providing a comparison signal to the microprocessor, and the microprocessor programmed for, providing a reference voltage signal for the comparator corresponding to a desired hack e.m.f. voltage for causing the d.c. motor to drive the postage printing drum at a desired constant velocity, energizing the power switch with a first signal for causing the d.c. motor to accelerate the drum at a substantially constant rate to substantially the desired constant velocity from the home position thereof during a first predetermined time interval, determining whether the back e.m.f. is greater than the reference voltage, energizing the power switch with the first signal for a second predetermined time interval if the back e.m.f. voltage is not greater than the reference voltage, and energizing the power switch with a second signal for a third predetermined time interval if the back e.m.f. voltage is greater than the reference voltage and delaying energizing with the second signal if the back e.m.f. voltage is not greater than the reference voltage, thereby causing the d.c. motor to continue driving the drum at substantially the desired constant velocity.
