🔁The new quad motor system developed by Rivian features a dual motor configuration.
🌡️The new system utilizes a pressurized oil cooling system for better heat dissipation.
🔌The old system used ethylene glycol and water coolant, while the new system uses oil for cooling.
💡The new system reduces the number of welds in the motor housing, resulting in increased efficiency and cost savings.
🧩The new system allows for independent control of each wheel, eliminating the need for a differential.
What are the differences between the old and new quad motor systems of Rivian?
—The old system had four motors, while the new system features a dual motor configuration. Additionally, the cooling system has been improved, with the new system using a pressurized oil cooling system instead of ethylene glycol and water.
Why did Rivian switch to a dual motor configuration?
—Rivian moved to a dual motor configuration to improve efficiency and reduce costs. By consolidating the motors into one unit, they were able to achieve better performance and heat dissipation.
How does the cooling system of the new quad motor system work?
—The new system utilizes a pressurized oil cooling system. Oil is passed through the motor components, including the stator and rotor, to extract heat and keep the system operating at optimal temperatures.
What are the benefits of reducing the number of welds in the motor housing?
—Reducing the number of welds in the motor housing increases efficiency and reduces costs. It simplifies the manufacturing process and improves reliability by minimizing potential points of failure.
What is the advantage of independent wheel control in the new system?
—Independent wheel control allows for better traction and handling. Each wheel can be controlled individually, providing superior performance in various driving conditions.
