CONSTRUCTION

ISCAD describes a paradigm shift: 48 V instead of 800 V and bars instead of copper coils in the stator. The bars of the stator cage are supplied by dedicated power electronics units.

Another special feature of the construction is the integration of the power electronics in the motor through which an optimal utilization of the machine volume is achieved.

DATASHEET ISCAD V50

TOP THREE

Unlike the high-voltage system, 48 V is safe to touch and there is never risk of an electric shock. In addition, integration and maintenance are much more cost-effective, as no specially trained high-voltage technician is required and no high-voltage safety measures are necessary.

Yes, ISCAD V50 with 50 kW continuous power and 80 kW peak power is available for order now. There is also the option of purchasing a modular and customizable drive solution, which contains everything you need for the efficient and reliable propulsion of your electric boat. Please feel free to send us an enquiry.

ISCAD V50 has 3 connectors each for plus and minus pole, 2 x 16mm connectors for water cooling and 3 M12 plugs.

GENERAL

ISCAD V50

Yes, ISCAD V50 has a CE certificate and the functional safety is certified according to the industry standard IEC61508.

This is strongly dependent on the type of boat. Our demo boat reaches a top speed of 28 kn (52 km/h). More information in our speed test video.

The peak power is available for 15 seconds.

The motor is controlled via a proprietary CAN protocol.

At the moment, the ISCAD V50 drive is available with a continuous output of 50 kW. We will keep you informed about further power classes via our social media channels.

Yes, this is possible.

This depends on the connection of the boat. AC charging is possible without any problems. The charging time depends on the battery capacity and the charging power. To charge DC, an on-board charger has to be installed.

This depends strongly on the boat and the speed. With our demo boat (1150 kg/ 7.1 m length/ 30 kWh battery), for example, we get 90 km at an average speed of 5 kn (10 km/h). The capacity of the battery correlates directly with the range.

Integration

No. The entire system runs at a voltage of 48 V, which is safe to touch. Therefore, no high-voltage knowledge is necessary. However, you should have a good understanding of electricity in general or contact a specialist to avoid any harm e.g. to people, the drive, the boat and the batteries.

No. With ISCAD V50, the controller and the motor form a single unit.

The drive is water-cooled by means of a dual-circuit system. The inner circuit is cooled with water glycol and the outer circuit with sea water.

A short cable distance is essential for our system. For a cable length of 1 – 1.5 m, for example, 3 cables per pole with a cross-section of 95 mm² are recommended.

Batteries made of 48 V modules are optimal. We offer compatible battery packs for our ISCAD V50 in cooperation with partners. Please contact us.

Yes, this is possible.

Yes, this is possible.

ISCAD V50 is compatible with z-drives, saildrives, shaft and outboard motors.

This is optionally possible with a reduction gear or directly on the motor with a clamping flange. We will be happy to advise you on various options. We look forward to your enquiry.

A CAN interface with proprietary protocol is used.

Technology

ISCAD has simple bars in the stator instead of complex windings. The many bars make it possible to distribute the high currents on the DC side, which are necessary for very high power at 48 V, over many branches. The alternating currents can thus be generated very efficiently with common semiconductors.

No. ISCAD V50 has passed the emission test according to EN 55012 and the immission test according to EN IEC 61000-6-2. For the measurement of electromagnetic compatibility, the EU Directive 2014/30/EU applies as a basis. Check out our Video about the Emission and Immission test.

In the case of a 48 V battery, only a few cells are connected in series; instead, many strings are connected in parallel. There are actually several advantages to this: The design of the battery management system is simplified and the probability of failure of the entire battery is reduced. In addition, the arrangement of the battery packs in the boat can be flexibly designed, as the battery can be divided among many modules with small capacities.
