To increase efficiency and humanization of the work places, a new generation of single motor driven spindles for the cover spinning of elastomers with synthetic yarns or with natural yarns was developed. Based on the experience of the belt driven spindles, and on many years of know-how in the field of single motor driven systems, Temco have now launched the new MSE 150 series of spindles which has been designed – in accordance with its corresponding bobbin weight and bobbin geometry (up to 6.5” traverse) – for speeds up to 36,000 r.p.m.
Advantages of the MSE 150 spindle – increased productivity due to higher speeds of up to 36,000 r.p.m. – better yarn qualities due to constant speeds from position to position (speed difference < 1%), and reduced vibrations – optimized process due to an infinitely variable, frequency controlled driving system – higher efficiency due to essentially less yarn breaks – reduced operating costs due to less maintenance – noise emission reduction due to the lack of tangential belts and belt guiding elements – longer life of the spindle due to lower vibration levels in the spindle and on the machine – lower temperatures of the motor and of the bearings due to an integrated cooling system

Product characteristics Three-phase asynchronous motors with 3 x 250 Volt max. are being used as a driving system; these motors are speed controlled up to 600 Hz. In accordance with the respective case of application, motors with a shaft output of up to 250 Watt are available. The rugged and solid construction of the three-phase motors are particularly suitable for the special requirements of the 24-houroperation in cover spinning mills.

The electric power supply and control of the motor spindles is made by means of frequency converters which have been wired in a synchronous way with the feed rollers and take-up system. This means that the ramp-up time and ramp-down time of the machine is coordinated with the spindle and controlled centrally. The ramp-up and brake times are controlled infinitely variably. Each spindle has been designed for manual start/ stop. The braking period can be adjusted timewise by means of a regenerative brake.
various countries. The reduction of noise comes from the elimination of the tangential belt as well as the bearing elements to guide the belt. The integrated bearing assembly (i.e. the raceways of the bearings have been ground-in into the shafts and into the housing) is offering the advantages of more rigidity and of the higher dynamic load rating which both are prerequisites for the high speeds of up to 30,000 r.p.m. The bearing assembly is protected against dirt, thread laps and fluff by means of a double lip gasket and a rotating disc. Relubrication is possible.
Reduction of the noise by up to 6 dB(A) A special characteristic and feature of the single motor drive system is the striking reduction in noise by almost 6 dB(A), which contributes to more human working conditions for the operating personal, and which at the same time is complying with the strict noise proteciton laws being applied in the
The damping systems between the bearing and the housing as well as between the adapter and the spindle rail have been especially designed by Temco to reduce the vibrations and the bearing forces, by which the life of the spindle bearing assemblies is increased clearly and noticeably. This effect, too, is contributing to the reduction of the noise level.
Safe fastening of the bobbins and an ergonomic optimization are guaranteed by the newly developed one hand adaptor system. The force being necessary to change the bobbins is reduced considerably. Saving energy of up to 30 per cent A pot which encloses the bobbin, and which can be opened, helps to save further energy of up to 30%. And in addition, the noise will be reduced again. Temco’s above new spindle conception of the single motor driving systems is already being used in the latest generation of cover spinning machines. Thus renowned companies have already decided for the Temco MSE 150 motor spindle in their machine installations. Temco’s single motor driven spindle programme is completed by further spindle designs and constructions for special textile-technological applications.
