The drive circuits introduced by Portescap for the escap DC motor range provide four quadrant speed control and may also be used for position control.
They are specially designed to use the short electrical time constant of the motor. The ironless rotor structure gives linearity of the torque constant over a wide current range.
As there is no saturation effect, high peak currents give high peak torques that are needed for fast incremental motion, while at the same time there is no danger of demagnetisation of the stator magnet.
The ELD-3503 drive circuit includes a bipolar linear Tran conductance power stage for operation without generating electrical noise. Driver efficiency depends on the motor speed and torque. Speed may be controlled either from a tacho signal or by using R x 1 compensation.
