IEm Mobility Motors
Infinitum Electric is pushing the boundaries of motor technology with a liquid-cooled, smarter air-core motor design that can deliver premium performance for mobility applications. At a fraction of the weight of conventional motors, our IEm motors dramatically improve efficiency and reliability while also offering high-speed, excellent torque, and a modular design. As a result, IEm motors are well suited for drivetrain and propulsion and auxiliary motor applications for Class 1 -8 commercial vehicles as well as aerospace, marine, construction, and agricultural applications.


Commercial Vehicle and Other Mobility Applications
Propulsion Motors
IEm motors are designed for mobility applications including Class 1 to 8 commercial vehicles, aerospace and marine applications, and heavy machinery. Engineering teams can add power, from 50 to 250 kW, without significantly increasing the size and weight of the drivetrain. Using an axial flux design, IEm motors generate more torque and faster rotation in a smaller package. With our modular disc design, engineers can build multi-stator, multi-rotor motors that offer high power and increased performance. Our innovative design also allows for a highly efficient oil-cooling system that cools the interior stator, helping increase power density by three to five times.
Auxiliary Motors
EVs require up to 50 small electric motors to power infotainment systems, heating and AC, window controls, and even the power steering. This means small, lightweight auxiliary motors are critical for maintaining the efficiency of the vehicle. By etching copper coils directly onto the PCB stator, we eliminate the heavy iron core and copper windings used in conventional motors, cutting motor size and weight in half. This design also makes IEm motors highly reliable and durable. And, by using air-cooling technology rather than noisy fans, IEm motors keep noise low in today’s ultra quiet EVs.

Reimagining Motors with IEm
Motor development tailored to your specific mobility application needs
To keep pace with the demand for commercial vehicles that are more powerful yet more efficient, the ability to quickly iterate on designs and alter components based on changing needs is critical. This is why we collaborate closely with customers working on these applications, tailoring each IEm Series motor to meet the specific application needs. Our motors use a modular design with the flexibility to add the number of stators and rotors that best suit your power and torque needs. We also provide simple and cost-effective prototyping and production since any local contract PCB manufacturer can produce the motor, avoiding potential supply chain issues.
