Conveyance with electronic control for left and right motors

A conveyance (10) having dynamic braking, which conveyance comprises:

• a propulsion element (12a or 12b);
• an electric motor (26a or 26b) being operatively connected to said propulsion element;
• motor control means (332a or 334a), being connected to said electric motor, for supplying an effective driving voltage (209a) to said electric motor that comprises a plurality of voltage pulses (207a) to said electric motor that are interspersed with no-power intervals (217a);
• and
• motor-loading means (354a or 356a), being operatively connected to said electric motor, for placing an electrical load (213a) on said electric motor during a portion (233a) of a plurality of said no-power intervals while said motor control means continues to supply said voltage pulses to said motor;
• whereby
• said electric motor provides dynamic braking during said portions of said no-power intervals.

A motor drive (90a or 268a) of the type which includes an electric motor (26a), the improvement which comprises:

• motor control means (332a or 334a), being operatively connected to said electric motor, for supplying an effective driving voltage (209a) to said motor that comprises a plurality of driving voltage pulses (207a);
• and
• dynamic braking means (354a or 356a), being operatively connected to said motor, for applying dynamic braking pulses (213a) to said motor that are interspersed between respective ones of said driving voltage pulses while said motor control means continues to supply said voltage pulses to said motor;
• whereby
• said dynamic braking pulses provide dynamic braking for said motor drive.
