Product description
The starting-point for highly efficient outboards
|
The motors in the BaseTravel range are the stationary companions to the Travel models. They have the same excellent efficiency in the drive train but are connected just like conventional electrical drives via cable connections to standard lead batteries. Instead of a foldable shaft, they are equipped with a fixed shaft. As no lithium batteries are integrated into the BaseTravel models, they are considerably less expensive than the Travel motors. Additionally, they are also suitable for applications within the performance range of the Travel line, where higher battery capacity is required. |
The BaseTravel 401 model works with a voltage of 12 V, whereas the BaseTravel 801 model is operated at 24 V. A cable connection for standard lead batteries with integrated fuse is contained within the scope of delivery. Similar to the battery of the Travel model, the removable cable adapter serves as main switch of the BaseTravel model. A bridging cable is also delivered for serial connection of two lead batteries to each other (for BaseTravel 801). |

The BaseTravel also runs on lithium batteries
For uses where the mobility of the BaseTravel is important or for the use of back-up batteries, the motor can also be driven using the Travel replaceable battery, available as an optional accessory. Using the lithium high-performance battery, the BaseTravel motors achieve the same performance as that of comparable Travel models.
Background knowledge on calculating the range of electric motors:
The range and runtimes that can be achieved using electrical drives with specific battery supplies are calculated in four steps as follows:
- Calculation of the existing battery capacity: To calculate this, the power of the battery (in volts) is multiplied by the charge (in ampere-hours). A 12 V battery with 100 Ah therefore has, e.g. a capacity of 1,200 watt hours (Wh), while two batteries connected in parallel with a total of 24 V and 75 Ah each have a capacity of 1,800 Wh.
- Calculation of the required amount of energy: The input power required by the motor is considered in the next step. The BaseTravel 401 has, e.g. an input power of 400 watts. 400 Wh are therefore required for one hour runtime at full power.
- Calculating the range: An initial range can be calculated taking into account the speeds that can be achieved (compare the graphic on Page 25). For example, on a dragon sailing boat the BaseTravel 401 reaches a speed of 3.5 knots (6.5 km/h). With one 12 V battery at 100 Ah (resulting capacity of 1,200 Wh) it could therefore run in theory for 3 hours at full speed and cover a distance of 10.5 nautical miles (19.5 km). The range calculation for a 1,200 Wh lithium battery power supply would now be completed.
- Taking into account the lack of high-current resistance of lead batteries: Lead batteries have a relatively low resistance to high currents, i.e. their capacity drops significantly under their nominal capacity as soon as a consumer tries to draw higher currents from them. To calculate a realistic range, this effect must also be part of the calculation. If the appropriate specifications on high-current efficiency are not published in the data sheet of the battery then the diagram on Page 9 may provide you with assistance. To do this, the weight of the battery must first be determined, e.g. the weight for the 12 V battery at 100 Ah in the example above may be 90 lbs. If there is a power consumption of 400 W by the motor then there would be a high-current load of 4.4 W per pound of battery weight. The loss in effective capacity of the battery resulting from this can be estimated from the graph and should be less than 20% in the example, depending on the quality of the battery. The range that could therefore be actually achieved would then be approximately 8.4 nautical miles (15.6 km). Two rules can be derived from this calculation: Firstly, especially motors with a high input power require large lead battery banks to achieve reasonable distances. Secondly, drives with bad efficiency waste battery capacity in two ways: On the one hand, they do not sufficiently convert the used energy into propulsive power. On the other hand, they cause unnecessary high-current loads to the battery, whereby less capacity is available to be used.
