HBL’s motor expertise has grown from developing sophisticated motors for naval propulsion systems.
HBL offers two major technologies for EV motors.
Radial Flux Reluctance Motor
HBL’s Reluctance Motors are designed for high reliability and cost-optimized EV applications. With or without the use of a transmission, these motors can be integrated in hybrid or pure electric drives for medium and large commercial vehicles like buses and trucks
The Reluctance motors are a little heavier but very close in performance to PMSMs, and thus, offer high value for money. They can also withstand high ambient and / or operating temperature.
Currently, three motor ratings are available. New motor designs can be quickly developed, if needed, for any large application.
HBL’s PMSMs are designed for high-performance drives, using stators and rotors of a few magnetic diameters. The PMSM offers increased efficiency with no eddy current losses. This is achieved by utilizing an iron-free stator – we do not use steel laminations.
HBL offers a wide range of motors and they are scalable due to their modular design. Motors with larger power and / or torque can be assembled by stacking stators and rotors of the most suitable available magnetic diameter, on the same shaft.
Axial flux motors can generate exceptionally high torque at low / medium speeds. The short axial length and high power density make them ideal for Hybrid Vehicles and Pure Electric Vehicles.
PMSMs offer extremely high reliability. However they also offer a “fail safe” mission critical feature - even if one inverter or one stator winding fails, the motor continues to operate and the mission is not entirely jeopardized. The vehicle is able to function until a repair can be organized. This motor will never leave you stranded.
A key advantage in EV/Hybrid design is the effort to minimize the required battery size. PMSMs require less current for a given duty from the battery. This results in reduced battery size (lower cost) for a given mission or longer mission life for a given battery (improved return on investment).
