Empire Magnetics Submersible series stainless-steel step motors are 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 washdown motors are partially filled with oil to prevent liquid ingress. Motors intended for complete submersion are filled with oil and are pressure compensated via diaphragm or piston assemblies. 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 sizes (custom sizes available), with static torque ranging from 0.4 to 11.3Nm. 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.
