2 , offers the reliability,low noise and energy saving characteristicsyou ve come to expect from the W range,but with added VSM s perfectly matched motor andinverter has been designed to improve theperformance of machinery and mechanicalhandling systems as well as increase theefficiency and reduce the cost of fan andpump VSM package fits within the sameenvelope as the equivalent W motor , andhas the same facility for mounting theterminal box (now the inverter) on the top orthe side of the motor . This allows forconsiderable space-saving and flexibility, forexample, in fitting the motor to existing designs and installations.

3 The close electricaland mechanical coupling of the inverter andmotor means there is no need for extracabling, so you can avoid EMC problems andvoltage spikes. It s efficient, robust andeconomical - in short - everything you dexpect from a motor with the W symbol -and its fast user-friendly programming meansthat installation is simple and you need fine speed control, rapidresponse and acceleration, energy efficiencyor low noise operation, you ll find it all in theVSM W Crompton are an approvedmanufacturer of ac electric motors within theUK Government s Enhanced CapitalAllowance (ECA) wide range of single and multi-speedmotors are included on the UK EnergyTechnology List in addition to the check the ECA scheme time of purchase forcurrent Issue 1 Integrated variable speed W motorsCost saving no screened power cable required no cable length limitation.

4 Hence no cablechokes requiredComplete flexibility option available of three inverter positionsSpace saving no panel space required VSM is the same size as a standard W motorVariable speed motor replacing mechanical variatorVSM benefits and options3 VSM mounted controls optionsA variety of components can be locallymounted and fully wired to a 3-station diecast aluminium enclosure to provide controlat the motor itself. Choose from any 3 of thefollowing: stop push button start push button speed control potentiometer forward/reverse selector switch local/remote selector switch indicator lamp low/high speed selector switch manual/automatic selector switchMechanical optionsThe VSM can be fitted with all the normalmotor extras.
