Cast Iron Electric Motors / Double Speed Motors are engineered to deliver two distinct operating speeds within a single motor, making them ideal for applications that require flexible speed control without complex drive systems. Built with a rugged cast iron body and high-quality internal components, these motors provide exceptional durability, thermal stability, and long service life in demanding industrial environments.
Industries seeking a dependable Double Speed Motor in Saudi rely on these motors for manufacturing plants, heavy machinery, pumps, compressors, fans, conveyors, cranes, and process industries. With a wide power range and proven winding technology, double speed motors support efficient operation while reducing energy consumption and mechanical wear.
These cast iron double speed motors are available at Nassguard and supplied across Riyadh, Jeddah, Dammam, Jubail, Al Khobar, and throughout Saudi Arabia.
A double speed electric motor (also known as a dual speed AC motor) designed with special winding configurations that allow the motor to operate at two different speeds, typically through pole-changing or separate winding connections. This design eliminates the need for external speed controllers in many applications.
Double speed motors widely used where variable process requirements exist, such as low-speed start-up and high-speed operation, or normal and boost operating modes.
Wide Power Range: Available from 0.55 kW to 355 kW
Dual-Speed Operation: Two operating speeds in one motor
Cast Iron Construction: Heavy-duty housing for industrial use
100% Copper Winding: High efficiency and excellent thermal performance
Built-In Feet: Stable and easy floor mounting
European Make Open Bearings: Re-greaseable for extended life
Thermal Protection: PTC thermistor device for overheating protection
Industrial Continuous Duty: Designed for demanding operations
Double speed motors are available in different configurations based on application needs:
Dual Speed AC Motors: Ideal for fans, pumps, and compressors requiring two operating speeds.
Pole-Changing Motors: Provide speed variation by changing the number of motor poles.
Separate Winding Double Speed Motors: Allow independent speed control through dedicated windings.
Heavy-Duty Cast Iron Motors: Designed for high power and continuous industrial use.
These options help engineers select the right dual speed motor winding and connection for their specific process requirements.
Manufacturing & Processing Plants: Supports machines with variable operating speeds.
Fans, Blowers & HVAC Systems: Allows energy-efficient low and high-speed operation.
Pumps & Compressors: Improves process control and reduces mechanical stress.
Material Handling & Conveyors: Provides flexibility for different load conditions.
Heavy Industry & Utilities: Ensures reliable performance in continuous-duty environments.
Cast iron double speed motors comply with internationally recognized motor standards:
IEC 60034 – Rotating Electrical Machines
IEC 60034-1 – Rating and Performance
IEC 60034-12 – Starting Performance of Single-Speed Motors
IEC 60034-30 – Motor Efficiency Classes (IE)
ISO 9001 – Quality Management System
These standards confirm electrical performance, efficiency, thermal safety, and manufacturing quality.
