Product Description:

The STF5332-3748-61-56BC-CU is a permanent-magnet DC washdown motor manufactured by Kollmorgen and assigned to the STF Washdown Motors series. As a sealed drive element, it converts direct-current input into rotational mechanical power for conveyors, mixers, and indexing stations that must be cleaned with water and caustic solutions. The unit supplies constant torque without ventilation, allowing integration inside stainless enclosures or open frames where airborne contaminants or spray are present. Its compact 56C face couples to gear reducers and other driven equipment used with standard industrial frames.

Under continuous duty, the motor draws 4.6 A and develops 36.0 lb-in of shaft torque, which indicates the steady thermal load on the windings. When the armature is supplied with 180 VDC, the rotor stabilizes at a nominal 1750 rpm, matching common line-shaft speeds. The TENV construction relies solely on surface conduction to remove heat, preventing wash water from entering through fan openings. Electrical parameters of 2.40 Ω resistance and 32.00 mH inductance set time constants that the drive controller must follow for smooth current regulation. The NEMA face simplifies alignment with pumps, gearboxes, or couplings during installation.

Short bursts are supported by a peak armature command of 36.0 A, enabling temporary acceleration loads without exceeding insulation limits. Output capability reaches 1.0 HP, giving a clear ceiling for mechanical load selection. Current can be converted to torque with the 8.00 lb-in/A torque constant, which simplifies proportional loop tuning. The housing meets IP65 protection, so low-pressure wash streams and dust do not affect the bearings or windings. A 0.6250-inch shaft and a 0.188 × 1.38-inch key complete the power path for sprockets, sheaves, or direct couplings.
