FIELD: materials handling facilities; electric drives of long conveyor systems. SUBSTANCE: multiple motor drive has separate drives with squirrel-cage indication motors, differential reduction gears and DC machines Series DC windings of the latter are connected to common adjustable-voltage DC source. Additionally drive has tension station position pickups whose outputs are connected to field winding of DC machines through amplifier. Tension station position pickups are made in form of potentiometers with nonlinear output characteristic. EFFECT: enlarged operating capabilities. 2 cl, 2 dwg
