Francis klein & co supplies new generation stepper motor and stand- alone control module, manufactured by slo-syn, a division of warner electric sa of switzerland. Slo-syn represents the kml series of stepper motors. This stepper motor has holding torque between 1.2 and 8.2 nm as compared to old mo 60 and mo 90 standard motors with 0.53 to 3.9 nm. . There are 4 lengths available for size 23, and 3 for size 34. They are usable in full step, half step and micro stepping operation. They have typical step accuracy of 12 %, and their maximum speed is 6,000 min-1. These motors can endure twice the rated current without demagnetisation, thus enabling an instant torque peak equal to 200% of the rated torque. In most of the cases, a smaller motor can be used to provide the same output that enables cost reduction of up to 25 %. For precise positioning, the ss 2000 d61 stand-alone module is available. This module has an integral 6a/180 v drive capable of operating with ratings of 12,800 steps per revolution. It consists of 1 axis control card connected to two rs- 232 or rs-485 serial ports, and controls 8 inputs and 4 outputs with opto coupling. It is encoded using a language developed from basic. Integrators or designers of special machines are among the clients using this product. It also comes in a brushless version. The tdc series integrates a 4-quadrant amplifier with a continuous current capability of 4 or 8 a input in voltages from 90 to 240 v ac.
