Tesla – 4″ Submersible Motors

GENERAL DATA

• 4″ submersible asynchronous two-pole electric motor made entirely of AISI 304 stainless steel for the parts in contact with water.
• The thrust block and bushes are cooled and lubricated with a mixture of water and glycol.
• The rotor is mounted on a Kingsbury self-centring thrust block designed to withstand significant axial loads.
• The resin filled stator is housed in an airtight AISI 304L stainless steel casing with internal sleeve and outer casing and flanges.
• The 4GX version completely in AISI 316 stainless steel is available on request.
• The cable connector is removable for the purpose of quick and easy maintenance.
• The cable is certified to CSA & UL electrical safety standards.
• The motor is suitable for use with variable frequency drive (30 Hz – 50 Hz).
• For the single phase motors, the capacitor and manually resettable overload protection are in the electrical control box provided separately. Overload protection to be provided by the user for the three-phase version.

CONSTRUCTION FEATURES

• Canned resin filled stator housed in an outer casing and flanges in AISI 304L. The stator has 24 slots to ensure better elasticity and smooth operation; the copper conductors have a double layer of Class H insulating enamel.
• Kingsbury thrust block equipped with carbon clearance ring and oscillating pads in high-strength stainless steel machined by Tesla with a spherical lapping process.
  • From 0,5 HP to 1.5 HP: 2000 N
  • From 2 HP to 3 HP: 3000 N
  • From 4 HP to 10 HP: 6000 N
• Shafts with terminal in AISI 304/Duplex, with special surface hardening and polishing in the work area of the bushings. Squirrel cage rotor in aluminum for power ratings up to 3 HP and in copper for motors of power above 4 HP.
