High-Torque Design

Design C Torque Output delivers a minimum Locked Rotor Torque of 200%, providing exceptional starting capability to handle difficult-to-start loads with ease. With a minimum Breakdown Torque of 200%, it powers through peak load demands, delivering reliable performance in heavy-duty applications.

Multi-Mount Terminal Box Design

The terminal box is engineered for maximum flexibility, enabling quick and straightforward field adjustments to accommodate F1, F2, or F3 mounting positions.

Rugged Construction

Cast iron finned frame and bearing brackets, a fabricated steel fan cover, and a low-noise fan are paired with a corrosion-resistant, severe-duty coating system that uses an alkyd resin primer and an acrylic enamel finish, provides protection in demanding outdoor environments.

Multiple Frame Mounting Capabilities

Features multi-mount capability for drop-in replacement, including dual mount S-586/587 and quad-mount B-587/588/589/5810, with horizontal and vertical mounting options. Includes vertical jacking bolts, four-position dowel holes, and ample clearance between the box and floor for easy connection.

Ingress Protection

Oversized Bearings

Oversized 300 series bearings on both drive and non-drive ends enhance durability and extend motor service life.

Thermal Protection

Embedded 100 Ω platinum stator RTDs, two per phase terminated in an auxiliary box, help protect the motor’s insulation system from excessive heat and unsafe operation.

Humidity Protection

120V space heater is included in all frames.

Vibration Provisions

Designed for mounting vibration sensors (1/4” NPT) on each bearing bracket.

Drive Duty Compatibility 

The insulation meets NEMA MG1 Part 31 standards.  It can be paired with a UL-Listed Medium Voltage Drive, which features a motor-friendly multiphase neutral point clamped output.
