A permanent-magnet synchronous motor that drives the load directly is known as a direct drive motor. This type of motor eliminates the need for a transmission or gearbox.
As a result, the system’s moving parts are greatly diminished. As a result, the system operates more quietly, dynamically, and efficiently for a much longer period of time.
Direct drive motors are ideal for applications requiring strong acceleration and quick starts and stops.
This is so that they can accelerate the motor with less torque than geared motors, which have a higher torque to inertia ratio.
The Global Direct Drive Motors market accounted for $XX Billion in 2022 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2024 to 2030.
The creation of a small, light-weight direct-drive system that combines the motor, inverter, and brake into one unit for the growingly popular EV category was jointly announced by Hitachi, Ltd.
and Hitachi Astemo, Ltd. This makes it possible to fit the entire system into the wheel, bringing us that much closer to a civilization with no emissions.
The new motor’s world-class 2.5 kW/kg power density and lightweight design greatly reduce the weight gain often associated with in-wheel units while transmitting the high drive force required to operate an EV straight to the wheels.
Additionally, the suspension and other components can be left in their current configuration when switching to an in-wheel unit.
Motor power may be applied directly to EV operation because driveshafts and other intermediary systems have been removed.
Compared to current EVs, this minimises energy loss by 30% and extends the range per charge. In order to make use of the technology, which enables larger interior and battery installation spaces, Hitachi and Hitachi Astemo will continue their study.
The new direct-drive system will be incorporated into Hitachi Astemo’s already wide, global EV product selection in addition to the vehicle control technologies it has been developing.
