Electric Motors by RPM
Motor speed (RPM) directly affects torque output, system load, pump and fan performance, and mechanical integration.
Choosing the correct RPM ensures proper startup torque, flow and pressure control (for pumps & blowers), conveyor stability, and long-term reliability.
Crossman supplies 900, 1200, 1800, and 3600 RPM motors in ODP, TEFC, Explosion-Proof, and Washdown-Duty designs — all available in NEMA Premium efficiency and VFD-ready configurations.
Whether you're powering centrifugal pumps, positive displacement systems, conveyors, compressors, or industrial fans, proper RPM selection protects equipment and optimizes performance.
Browse Motors by RPM
Select the operational speed that matches your system requirements.
High-speed for pumps, grinders, blowers & compressors
Standard industrial speed — high torque, universal duty
Balanced torque & speed for high-load process equipment
High torque, low speed, ideal for heavy-load applications
How Motor Speed Affects Performance
Torque Output Lower RPM = higher torque
Load Type Compatibility Pumps, conveyors, blowers all scale differently
Noise & Vibration Higher RPM → more vibration and noise
Bearings & Life Speed impacts mechanical stress & heat
VFD Control Variable speed = improved efficiency & flexibility
System Efficiency Proper RPM prevents over-sizing & wasted energy
Torque and speed are opposites — RPM selection protects equipment.
Where Each RPM Range is Used
900 / 1200 RPM Heavy conveyors, agitators, mixers, crushers
1800 RPM Pumps, conveyors, compressors, industrial fans
3600 RPM Centrifugal pumps, blowers, grinders, high-speed equipment
