Motors & Drives Information

Submersible series stainless-steel step motors are uniquely designed to provide maximum operational reliability in marine and submarine applications. Their internally sealed design eliminates the corrosion and motor failure problems common to conventional steppers in fluid processing, washdown and complete submersion environments. Standard submersible motors feature air fittings that allow the motors to be pressurised for protection against external fluids, from simple mist to complete submersion.

An oil-filled version with pressure equalising diaphragm is available for more aggressive deep submersion applications.

Waterproofing measures for both motor versions include o-ring body seals and a double shaft seal.

The motors are available with feedback resolvers and conversion electronics, providing quadrature or binary motor position information.

Submersible motors are available in standard 23, 34 and 42 frame sises, with static torque ranging from 60 to 1600os-in.

Round mounting flanges are standard to simplify face sealing, while square flanges are available for compliance with NEMA mounting specifications.

These motors are compatible with most bipolar full step and microstepping motor drives.
