Shivam Autotech Unveils ER-Axle for Electric Mobility

Shivam Autotech enters the EV segment with its ER-Axle, an advanced solution for electric rickshaws. Combining an electric motor, differential, and control systems, it ensures efficient performance and sustainability.

Gurugram- Shivam Autotech Limited., a manufacturers of transmission gears and shafts and strategic manufacturing partner for a range of Original Equipment Manufacturers (OEMs) and Tier 1 companies. With over 25 years of industry expertise, the company serves notable clients, including HAL, Hero, Suzuki, and Volvo Eicher, along with Tier 1 suppliers like Bosch, VECV, Denso, and Mitsuba. 

Entered in EV segment with products like L3 Differential/AXLE with various sizes, Gear Box in various gear ratio & Shock Absorbers for E 2 wheelers from Munjal Showa (Group Company) Shivam Auto tech has made its space by supplying its components to EV manufacturers. 

An E-Axle, or Electric Axle, typically refers to a compact unit that integrates electric motor(s), power electronics, and sometimes a gearbox into a single housing. The "differential" in an E-Axle is the component that splits torque between the two wheels of an axle, allowing them to rotate at different speeds while delivering power from the electric motor(s).

In a traditional vehicle with an internal combustion engine, the differential serves the same purpose but operates with a mechanical drivetrain. It enables the wheels to rotate at different speeds during cornering.

In an E-Axle, the differential is often integrated into the housing along with the electric motor(s) and power electronics, optimizing space and efficiency. This integration enhances the compactness and simplicity of electric drivetrains, which is crucial for the overall performance and packaging of electric vehicles.

"ER-Axle" stands for "Electric Rickshaw Axle." It refers to an axle assembly in an electric rickshaw (EV) that houses an electric motor to drive the rear wheels.

In electric vehicles, the ER-Axle plays a critical role in propulsion by converting electrical energy from the battery into mechanical energy to drive the vehicle. It consists of components such as the electric motor, differential (if applicable), and associated electronics and wiring.

The design of an ER-Axle varies depending on the specific vehicle model and manufacturer, influenced by factors like power output, efficiency, mountings, IP ratings, and packaging constraints.

Here’s a simplified overview of how an ER-Axle works:

1. Electric Motor: The ER-Axle contains an electric motor that receives electrical power from the vehicle's battery pack.
2. Power Conversion: Electrical energy from the battery pack is converted into mechanical energy by the electric motor. This involves the motor's stator (stationary part) and rotor (rotating part) interacting to create rotational motion.
3. Transmission: Some ER-Axles may include a transmission to provide multiple gear ratios for optimized performance and efficiency. This can be either single-speed or multi-speed.
4. Differential: In single ER-Axle vehicles (typically rear-wheel drive), the differential allows the wheels to rotate at different speeds during cornering while still receiving power from the motor.
5. Drive Control System: The ER-Axle is managed by the vehicle's onboard motor control system, which regulates power delivery based on driver inputs, vehicle speed, traction conditions, and other factors.
6. Regenerative Braking: Many electric vehicles utilize regenerative braking, where the electric motor acts as a generator during braking, converting kinetic energy back into electrical energy to recharge the battery pack. The ER-Axle plays a vital role in this process. 

Overall, the ER-Axle is essential for propulsion and movement control in electric vehicles. Unlike traditional internal combustion engine systems, it operates using electrical power, contributing to environmental sustainability.
