VECTOPOWER electric drive

The general advantages of an electric drive are clear: torque from a standstill, higher efficiency and fewer emissions than combustion engines. The challenges start with real-life use:

  • How do you use the available installation space in the most effective way?
  • Can the drive components handle the rough environment and the critical operating conditions? 
  • Which electric drive achieves an optimum battery range? 
  • How can a low-priced electric drive be realized for series production? 

The engineers at ARADEX are working on answers to these questions for you, using the high-performance electric drive and extensive experience with electrical mobility applications as a basis.

Compact and powerful - the inverter

The VECTOPOWER inverter offers an extremely high power density: It has an output of 250 kW with a volume of only 10 l. The high power density and the compact dimensions save space – which you can use for more batteries, for example. 

Technical data

  • Outputs up to 250 kW 
  • Very compact dimensions of approx. 262 mm * 98 mm * 394 mm (W*H*D)
  • Currents of up to 550Arms
  • Battery voltages of up to 720 V DC 

Maximum torques and speeds – the electric machine

The VECTOPOWER electric machines also offer strong performance data. The electric motors are precisely adapted to the requirements of your application. 

Field-weakening PM synchronous motors

The VECTOPOWER PM synchronous motors stand out as a result of their optimum efficiency at all operating points. 

The high-field weakening ability of the motors allows maximum speeds. In particular, the VECTOPOWER PM synchronous motors with buried magnets and utilizing the reluctance torque offer a very high power density.

High-efficiency asynchronous motors

The VECTOPOWER asynchronous motors achieve the efficiency and power density values of good PM synchronous motors. The high overload capability allows more compact motors. In the case of strong peak loads, an asynchronous motor is much more robust. 

Areas of application

  • Electric cars and vans 
  • Light aircraft
  • Fun vehicles and racing 
  • Boats and ships 

Higher battery range due to high efficiency 

The VECTOPOWER electric drive takes advantage of interactions in the system and thereby achieves a very high efficiency. This saves energy especially in the partial load operational range that is important for consumption, for example in stop-and-go traffic. The high efficiency allows greater ranges or the use of smaller and thus cheaper batteries.

Low-price series production 

The VECTOPOWER electric drives allow considerable material savings, e.g. through the use of high-efficiency asynchronous motors. This enables a low-priced series production.
