Worm Geared Motors

NMVRV NMRV and NMRV POWER worm gear reducers currently re-present the most advanced solution to market requirements in terms of efficiency and flexibility. The new NMRV Power series, also available as compact integral helical/worm option, has been designed with a view to modularity: low number of basic models can be applied to a wide range of power ratings guaranteeing top performance and reduction ratios from 5 to 1000. SW Traditionally known as the producer of a wide range of mechanical variators and helical cast iron inline geared motor units, Spaggiari Trasmissioni expanded its product range, after being taken over by Motovario, by adding an aluminium worm gear unit named SW. This new product, which complements the Motovario NMRV gear reducer, has a shaft height between 30 and 110 mm (Baugrößen 030 bis 105) and a compact round smooth body casing design that reduces the space as much as possible. For better reliability and compatibility/effectiveness of supply, the gearing, the bearings, the motor flange and the accessories are those of the NMRV series. NMRX & SWX The need to provide geared motors suitable for use in wet and corrosive environments has led Motovario to design a new product range specific to these fields. These products use materials, surface treatments, components and mechanical process for the motor and gearbox to increase both resistance and reliability.

Motovariators and Inverter Motors

Motovariators: cast iron and aluminium series With the high reliability due to 45 years experience of manufacture, VAR series motor variators represent a viable alternative to electronic drives. These units are EMC electrically compatible with ease of operation and maintenance. The cast iron S series, includes wide range of models: such as flange, foot and compact mountings, available in seven sizes from 003 to 100, with solid input shaft or motorized options too. Differential version SD series, allows to work in applications with speeds nearly to zero. The low cost and lightweight aluminum versions TXF series, are available in size 002, 005 and 010. Inverter motor Designed for multitudes of applications, Motovario inverter-motor is made with high-quality components and controlled by specific software that minimizes the power loss. The inverter is vectorially controlled to ensure a constant motor torque in all working conditions, with a frequency range from 2 Hz to the motor’s rated frequency. Can also be utilised to over speed motors up to 100 Hz. The unit is provided with as standard protection devices that are automatically triggered by over-temperatures, over-voltages and over-currents to prevent the unit from being damaged. Proven to be the most cost effective and reliable solution.
