Low-vibration motor Innomotics HV C air-cooled
Extremely reliable, low vibration levels and flexible – with a unique

High voltage motor Innomotics HV C air-cooled
Innomotics HV C air-cooled is an ultra-compact, extremely reliable high voltage motor for non-hazardous areas, including Ex zones 2 and 22 (Ex ec and Ex tc), with a power density 10-15% higher than other motors in the same size. The innovative rib and tube cooling concept, as well as a vibration-optimized design concept enable flexible integration into various plants and industry applications.
Benefits at a glance
- The highly flexible motor design of Innomotics HV C air-cooled allows for project-specific adaption to customer interfaces (e.g. variable junction box position), enables simplified installation and increased flexibility in plants and systems.
- The innovative cooling concept enables a compact and lightweight motor design (optimized by FEM analysis) that increases power by up to 15% and extends component life without changing overall size.
- The Innomotics HV C air-cooled impresses with the vibration-optimized design of the motor, the cable routing inside the motor and the compact, service-optimized terminal box with many possible positions.
- A uniform platform design for compact, air-cooled motors with or without explosion protection reduces costs over the entire life cycle – from planning and procurement, through engineering and plant integration, to service, warehousing and spare parts management.
- The Innomotics HV C air-cooled extend the range beyond existing flameproof and water-cooled versions.
- The Innomotics HV C air-cooled completes our compact motor platform, which consists flameproof and water jacket cooled motors, with an air-cooled version.
- The cooling system of the Innomotics HV C air-cooled combines rib and tube cooling with an internal cooling circuit to realize the most compact design possible with a small footprint while reliably avoiding hotspots.
- The engine impresses with optimized engine cooling using an advanced fan design. In contrast to conventional concepts, this significantly reduces motor temperature and optimizes the power density.
- Thanks to optimized temperature distribution, the Innomotics HV C air-cooled has an extremely high-power density and an extremely long service life. Even in extreme environments, the Innomotics HV C air-cooled runs very safe and reliable.
- Innomotics HV C motors are in integral component of Inspire IQ, the digital platform for optimizing drive systems.
- The Innomotics HV C motors have an optional connectivity Innomotics Connect 600 module for integration into the digital, cloud-based solution. This uses temperature and vibration sensors to capture and process data such as bearing temperatures, winding temperatures and housing vibrations and transmits this information for analysis in the cloud.
- The integration into digital system concepts of our customers, by using Inspire IQ, enables maximum plant and system transparency. Cloud-based digital expert analysis will increase availability, productivity, efficiency and performance of our motors and your application as well as improved service efficiency by using predictive maintenance.
- The Data Matrix Code enables quick and easy access to individual motor data via mobile devices.
