Code: C31/40 Description: Electrospindle C31/40 Technical specifications: GENERAL INTRODUCTION The electrospindles series C31/40 have been designed to generate a high power with limited overall dimensions. These features, joined to the high rotational speed, make these electrospindles the best solution for the machinery of wood, aluminium, and PVC. SERIES C31/40-SB: for rotational speed from 12.000 to 18.000 rpm where the prevalent load is radial load. SERIES C31/40-DB: for rotational speed from 12.000 to 24.000 rpm where an axial load is present. TECHNICAL FEATURES STATOR: Three-phase induction motor, insulation class F. ROTOR: squirrel cage rotor balanced according to ISO 1940 norms: balancing grade 2.5. For special applications we can supply motors with lower balancing grade. FRAME: self enclosed construction. The frame is obtained from an extruded aluminium bar. COOLING: shaft driven fan cooling. PROTECTION: IP 54 BALANCING: standard balancing with half key. COMPRESSED AIR COOLING: it is avaible on both version DBS and DBL allows a big reduction of the noise level joined to a very efficient cooling. This option allows the installation of the motor in a misty environment. COMPRESSED AIR FRONT SEALING: it is available in the DBL version only and it makes a barrier against the penetration of the fluids inside the front bearings. If it is requested together with the compressed air cooling it allows the installation of the electrospindle in a misty emvironment with indirect water jets. |
