Documentation
Application
Axial brushless electric motors can be used in devices such as:
- Unmanned underwater vehicles
- Military aircraft
- Wheeled and tracked robotic systems
- Civil electric transport
- Special unmanned vehicles
- Electric helicopters
Advantages
AX Drive axial permanent magnet brushless motors offer a number of advantages:
- The torque is up to 1000 Nm due to the innovative design of the motor
- High rated power, which is one of the highest in the class, at the level of the best world analogues, is 130 kW
- Use as a direct drive
- Liquid cooling of the stator windings
- The ability to work in generator mode
- High specific power and torque values
Features
The axial circuit has high efficiency and high specific torque. This is due to the cubic dependence of the increase in torque with an increase in diameter, whereas the torque increases quadratically in a machine with a radial magnetic flux.
Electric machines with axial magnetic flux may be used as traction motors for land, air and water transport, as well as in special equipment.
The key feature of AXD brushless electric motors is their high power density: up to 2.61 kW/kg in nominal operation and up to 6.19 kW/kg in peak operation.
