Electric traction motors are the powerhouse behind electric and hybrid vehicles. They convert electrical energy into the mechanical force that’s crucial for propelling the vehicle.
When you compare it side-by-side with traditional internal combustion engines, electric traction motors provide a clean, efficient alternative. This is because traditional internal combustion engines rely on fuel combustion, which produces harmful emissions, generates excess heat, and requires complex mechanical components such as pistons, crankshafts, and exhaust systems.
Today, these motors are even more powerful. Let’s discuss the functionalities of electric traction motors and the value they add to the EV industry.
How Electric Traction Motors Work
The way an electric traction motor runs is basically through the rotor and stator. The stator stays fixed. It has windings that carry electric current to generate a magnetic field. This magnetic field causes the rotor to turn, and thereby produces the mechanical motion that powers the vehicle.
To enhance efficiency, ENNOVI’s Motor Stator Busbar simplifies connections to the stator windings, reducing wiring complexity and improving reliability. Its compact design also saves space and weight, meeting the demands of modern EVs.
Aside from this, ENNOVI’s Phase Busbars support consistent power flow by enabling multi-phase connections between the motor and drive module.
Benefits of Electric Traction Motors in EVs and Hybrids
One of the benefits of electric traction motors is their remarkable efficiency as compared with ICEs. They convert over 85% of electrical energy into mechanical energy, which is already a notable improvement over the efficiency of gas combustion engines. This means longer range and lower operating costs for manufacturers, making EVs and hybrids an attractive and far better alternative.
There’s more to that. Electric traction motors also generate far fewer emissions than traditional engines. This bodes well for organizations that need to comply with environmental regulations.
ENNOVI’s Flexible Busbars have been innovated to absorb vibrations and accommodate thermal expansion. Doing so makes the component well-suited for the demanding conditions of EV operations.
Furthermore, the Phase Busbars from ENNOVI improve reliability by seamlessly integrating control circuitry into their structure, simplifying assembly, reducing weight, and enhancing overall motor performance. By supporting stable power distribution under high-stress conditions, they contribute to the prolonged durability and reliability that are critical for EV and hybrid traction systems.
