Induction vs. SynRM: The Under 2 HP Payback Pursuit
For motors under 2 HP, does the efficiency premium of SynRM justify the higher system cost over a…
Induction Motors, Synchronous Reluctance (SynRM), and MV/HV motors.
Application-specific OEM/ODM customisation for industrial engineering integrators.
Volenza's motor platform is designed from the ground up for OEM integration. We work with engineering teams at the specification stage — not just as a catalogue supplier, but as a design partner who understands your torque curves, duty cycles, and enclosure constraints.
Every motor variant is available with custom winding configurations, frame adaptations, and factory-integrated drive options. Induction motors cover IE3/IE4; SynRM delivers IE4/IE5 with near-zero rotor losses; MV/HV motors meet the upcoming IE4 standard for large-power applications.

| Best Applications | Pumps, Fans, Conveyors, Compressors | Variable pumps, Agri systems, Process fans | Blowers, Pumps, Pulpers, Compressors, Fans, Extruders |
* Meeting upcoming IE4 IEC standard.
Torque-dense, cost-effective, and rugged. IE3/IE4 squirrel-cage rotors with proven reliability for fixed-speed and VFD-driven applications. The default choice for pumps, compressors, and fans.
Medium and high voltage motors. Drive optional — suited for large-power fixed and variable-speed applications with IC611 and IC81W cooling systems. Up to 2000 kW.
IE4/IE5 class efficiency with virtually zero rotor losses. Synchronous Reluctance motors require VFD operation and deliver outstanding energy savings in variable-speed duty cycles.
* Meeting upcoming IE4 IEC standard.
Volenza's ODM platform is built for OEMs who need more than a standard catalogue motor. We support your engineering team from specification through production, offering:
