Braking system for a DC motor

A braking system for a DC motor including first and second terminals, said braking system adapted to be connected across the first and second terminals of the DC motor when the DC motor acquires a braking mode of operation, said braking system including a current control element operative to regulate a magnitude of a current passing through the windings of the DC motor when said braking system is connected across the first and second terminals of the DC motor, said current control element including:

• a switch capable of selectively acquiring a first operative state and a second operative state, in said second operative state said current control element manifesting a substantially higher impedance to the passage of current through the windings of the DC motor than in said first operative state;
• a control unit in operative relationship with said switch for:
• a) causing said switch to switch repeatedly between said first and second operative states when the DC motor rotates at a speed above a certain threshold;
• b) causing said switch to acquire and maintain said first operative state when the DC motor rotates at a speed below the certain threshold.
