The 'M' Series High Voltage Motor
TEFC Squirrel Cage High Voltage Induction Motor
A new
range of high efficiency Totally Enclosed Fan Cooled squirrel cage
induction motors, jointly developed by Laurence, Scott &
Electromotors (UK) and Marelli Motori (Italy)
The 'M' Series
motors reach new standards or performance (97% efficiency on larger
sizes).Noise levels as low as 80dBA are standard, starting current
designs down to 300% FLC are available on request.
Competitively priced through aggressive cost reduction
programmes, rationalised component sourcing and pre-engineered
manufacturing to standard specifications, customised as required at
final assembly.
The 'M' Series motors are suitable for the
widest possible range of industrial applications. Standard designs
are suitable for EExn / IP56 without additional costs. Design
variants for -50C or +60C permit use in even the toughest
environments world-wide.
Rationalised production and
component procurement makes for shorter supply chains and hence
better lead-times. Standard M Series motors are now available
Main Features
- Advanced Design - Low Noise & Vibration
- Low Running Cost - High Efficiency
- Long Life - Heavy Duty Construction
- Wide Application - Mechanically Compatible with alternative equivalent machines.
