13. A separation module for use with a lottery ticket dispensing unit for dispensing a continuous strip of lottery tickets interconnected by perforation lines, comprising:
a drive roller and an opposed idler roller with a nip defined between the drive roller and idler roller;
a motor geared to the drive roller, the motor switchable between a convey mode wherein the drive roller engages and conveys the leading ticket through the nip to a separation position and a brake mode wherein the motor provides a reverse retarding force to the drive roller thereby braking the drive roller against an attempted reeling of the lottery tickets from the dispensing unit;
a controller operable to switch the motor between the convey mode and the brake mode; and
the motor and controller configured such that in the brake mode, power to the motor is interrupted and windings in the motor are short-circuited, wherein rotation of the drive roller from the attempted reeling of the lottery tickets converts the motor to a generator, the short-circuited windings creating a load on the generator that produces the retarding force on the drive roller.
