Volabo Launches ISCAD Based Intelligent-Stator Drive Motor


  • Volabo has introduced a new stator drive motor based on Intelligent Stator Cage Drive (ISCAD)  technology
  • The length of the motor is 33 centimetres and this small size results in a compact housing for motors and associated electronics

With the fourth generation of its innovative electric drive, Munich-based start-up Volabo GmbH has been able to reduce the size and weight of the integrated power electronics by more than 50 per cent.

Shrinks size and weight of the motor

Generation 4 of Volabo’s Intelligent Stator Cage Drive (ISCAD) is considerably more compact than its predecessor. According to the company, the size and weight of the power electronics have been reduced by more than 50 per cent. In addition, the power electronics compartment has been significantly improved. The compartment also contains the central intelligence of the electric motor. With a length of only 33 centimetres, the engine can now be integrated very well into various vehicles.

Differs from conventional electric drives


According to the company, Volabo’s 48V stator drive motor concept for the electric drive differs from conventional electric drives. ISCAD is an electrically safe and cost-effective drive without rare earth magnets. The motor does not contain copper windings in the stator. Instead, it uses the fixed part of the electric motor. Volabo uses aluminium rods that can be individually controlled by the speed controller. This allows the driver to dynamically adapt the load profile. This contributes to an efficient drive.

Increased degree of integration

The complete integration of the control electronics into the power electronics has further increased the degree of integration. The drive is now being tested on the test bench. The driver of the vehicle has been replaced by the ISCAD prototype.

High-temperature TRIAC For IoT and Home Automation

Motor length is measured to 33 cm 

The length of this motor is 33 centimetres. This small size results in a compact housing for motors and the associated electronics.

Florian Bachheibl, the managing director for Volabo explained,

This way we achieve a high power density and the drive unit can be easily installed on the axle, as we have shown with the example of the demo vehicle. The new generation also consists of fewer components, which makes the power electronics both more cost-effective and more robust. With this fourth generation, Volabo is taking an important step towards the product. ”

Since the power electronics are now based on more compact modules, the appropriate number of modules can be mounted depending on the power class of the drive. The drive technology is thus well scalable and can be used in various areas such as marine, automotive or off-road.
