SSP

SSP is the only drive without feedback, guaranteeing absolute accuracy. The drive features the properties given below without speed feedback. No encoder, resolver or any other speed transducer is required. This makes the SSP a unique drive that may be used in a large variety of applications which have so far required motors with feedback.

Drive characteristics

The drive is the standard Blast-E, programmed with a special control technique developed for the SSP motor

Motor characteristics

Efficiency : An excellent feature of this revolutionary motor is the higher efficiency, even if the same contruction materials as for the normal induction motor are used.

Inertia: The motor inertia is 30 to 50% lower (according to the size) than an asynchronuos motor having the same power.

Strength and maitenance: Having no brushes, electronic parts, magnets, the motor is as reliable as an induction motor and does not need periodical servicing, expept for the bearings.

Torque ripple : Between 1% - 2% compared to the nominal torque, which makes SSP comparable to the best servomotors.

Position Accuracy: The error between two motors shaft positons is about ±1,5°; the error repetition on the same position is around ± 0,1°÷ 0,2°.This means that the error is non cumulative.

Speed Accuracy: Speed is controlled with error £ 0.01% (1:10.000) and keeps a good motion roundness at low revolutions. Such characteristic is kept from 0 (zero) up to 2 times the nominal motor speed (running at constant power) with torque values from 0 to 2 times tha nominal motor torque.
