Description

SD100 Motor – 1 to 400 HP, Cast Iron Frame, IP55, Inverter Duty | Hazardous Location Rated

The SD100 Motor series delivers reliable and durable performance across a wide range of industrial applications. With power ratings from 1 to 400 horsepower (0.75 to 298 kW) and availability in NEMA frame sizes 143 to S449SS, this motor is designed for heavy-duty operations and harsh environments. Its cast iron frame construction ensures mechanical strength and long operational life, even under demanding conditions.

Rated IP55 for protection against dust and water ingress, the SD100 motor is also engineered to operate safely in hazardous environments, complying with Class I, Division 2 standards as standard. Frames sized 280–400 include Class II, Division 2 compliance, with optional extensions for other frames, making it suitable for dusty or explosive atmospheres.

Corrosion resistance is enhanced through the use of zinc-plated hardware, epoxy paint coating, and a stainless steel nameplate. The motor features a diagonally split cast iron terminal box for easy access and long-term durability.

Internally, the motor utilizes Class F insulation with a Class B temperature rise, optimizing thermal performance and longevity. The SD100 is fully compliant with NEMA MG1 Part 31 inverter duty standards, supporting 20:1 variable torque and 4:1 constant torque speed control ratios, offering exceptional versatility for both constant and variable load applications.
