Vitesco Technologies introduces the Rotor Lock Actuator, a groundbreaking module that combines park lock, rotor position sensing, and an optional brush system for electric axles. This innovation reduces complexity, saves space, and lowers costs for electric vehicles. The new module will be showcased at the SIA POWERTRAIN 2024 in Lille, France, from June 19 to 20.
Key Highlights:
- Three-in-one module: Combines park lock, rotor position sensing, and an optional brush system.
- Cost and space efficiency: Relocates park lock functionality to the rotor shaft, streamlining system design.
- Enhanced integration: Facilitates additional functions like the brush system for EESM and inductive Rotor Position Sensor.
- High reliability and safety: Incorporates sensing redundancy, robust cybersecurity measures, and advanced diagnostics.
Comprehensive Functionality and Cost Efficiency
Most electric vehicles today use a mechanical park lock in the reducer gearbox, which occupies significant space. The Rotor Lock Actuator relocates this function to the rotor shaft, creating a more streamlined and cost-effective design.
Robert Paul, Head of the Actuation business unit at Vitesco Technologies, states, “The key to the success of e-mobility is the reduction of costs and complexity. By combining up to three functions in one product, our Rotor Lock Actuator enables us to offer high functionality while optimizing both packaging space and costs.”
Optimized Integration and Safety
The end-of-shaft position on the rotor allows for a smaller actuator, easily integrated into the vehicle’s drive. This mechatronic integration minimizes space requirements, facilitating additional functions like the brush system for EESM and the inductive Rotor Position Sensor. This eliminates the need for separate control units, sensors, and harnesses, further saving costs.
With sensing redundancy, cybersecurity measures, and internal diagnostics, the module’s reliability and safety are assured. Driven by a 12 V DC motor, the Rotor Lock Actuator integrates seamlessly into drivetrain and communication networks. The inductive Rotor Position Sensor enhances vehicle range through optimal motor control, and the module improves parking safety by reducing vehicle movement when engaged. The lock activates and deactivates in less than 250 milliseconds, preventing accidental engagement while driving.
Presentation at SIA POWERTRAIN 2024
The Rotor Lock Actuator will debut at SIA POWERTRAIN 2024 in Lille, alongside Vitesco Technologies’ High-Voltage Box and EESM rotor. The High-Voltage Box, set to be supplied to the Renault Group from 2025, offers a new approach to vehicle charging and conversion electronics. The EESM rotor, free of rare earth magnets, presents an economical option for high-performance electric vehicles.
Vitesco Technologies continues to lead in advancing electrification solutions, demonstrating innovation and efficiency at SIA POWERTRAIN 2024.
