Special Features of the motorzoo 12V-01×0 Electric outboard
The motorzoo 12V-01×0 electric outboard is a simple trolling motor.
It features an easy, simple design with the electric motor directly connected to the vertical drive shaft, which is eared to the propellor at the bottom :
- Light weight construction. No heavy chassis like conventional petrol motors. Small size electric motor.
- Electronics protected from elements. The motor itself sits at the top of the drive shaft elevated as high as possible from the water.
- long shaft design. The long shaft design suits small dinghies, and/or fixture to external brackets on small sail craft
It can be used on a dinghy in shallow waters, or on a bracket attached high to the transom of a yacht up to 5 meters, as an auxilliary motor.
Overall, the design approach to the 12V-01×0 electric outboard has been to produce a lightweight motor that can be powered by standard 12 Volt batteries.
What do you need to know about electric outboard motors?
There are two types of electric outboard motors. That is, trolling motors, and performance motors.
- Trolling motors. These will produce limited thrust because of their limited power and propeller configurations.
- Performance motors. Will draw more current and therefore produce more power, and can support larger propellors with a greater pitch, to produce more thrust.
You might expect a trolling motor such as the 12V-01×0 to drive a dinghy of up to 3 meters in length, with a total weight of up to say 200kg, to a speed of up to 4 knots.
But not much faster. Performance create more torque, and are designed to drive larger craft, up to 15 meters, with greater weights, up to 4,000kg, to greater speeds.
The maximum speed achievable will depend on factors such as: watercraft displacement; waterline length; motor speed; propeller diameter and pitch, and; other factors.
The differences between electric outboards and petrol driven outboard engines.
Electric outboard motors are very different to petrol outboard motors, on a number of levels:
Torque
Electric outboards maintain a higher torque throughout the RPM range, and will have a higher peak torque for a given power output.
Efficiency
Electric outboards operate at about 80% efficiency, with about 20% being lost as heat.
With petrol outboards, only about 25% of the energy converts to propulsion, with about 75% lost as heat.
Emissions
Electric outboards have no noxious emissions, whereas small petrol motors generate lots of noxious emissions.
These emissions include unburnt hydrocarbons, SO2, and NOx. It’s not all about CO2.
This is why the sale of two-stroke motors have been banned in Australia.
Noise
Electric outboard motors operate at much lower noise levels than petrol motors, especially when the motor unit is immersed underwater.
Complexity
Electric outboard motors have very few moving parts, whereas small petrol engines, especially four-stroke ones, have an excessive number of parts, for their small size.
Power
Larger petrol engines (of 50hp or more) have the advantage of delivering the power required to get watercraft planing at high speeds for long periods.
This is why electric outboards on more than 20hp power rating are not common.
Why not just convert petrol outboards to electric?
The power characteristics of electric outboard motors are very different to those of shaft driven petrol outboard.
As mentioned above, the torque/RPM profile is different to start with.
And it has been found that the typical chassis seen with petrol outboards is not very suitable for conversion to electric motor use.
The traditional chassis was found to vibrate excessively when electric motors are fitted, and so a new design approach was required.
The holistic design approach of the 48V-03×0 electric outboard has allowed the introduction of performance enhancing features as mentioned above.
And it has also allowed the removal of certain features that contribute little or nothing to the motor performance.
Power considerations.
The motorzoo 12V-01×0 electric outboard is the smallest of our budget range of electric outboard motors
- The 12V-01×0 has a power rating of 1.0 kilowatts.
- The motor draws a peak current of 20 Amps, and therefore requires a battery of sufficient voltage to meet these requirements.
- This is why uses a 12V (12 Volt) Lithium-Iron-Phosphate (LiFePo) power supply.
It is important that the battery power supply is able to deliver the peak current of the electric motor that it powers. Otherwise there could be damage to the battery management system.
- A 30 Amp hour (12v30Ah) LifePo Battery will typically be able to deliver a peak current of 40 Amps.
- Therefore, a minimum of one 12v30Ah battery would be required for the 12V-01×0 motor.
- The single 30Ah battery will deliver peak current of 40A for about 45 minutes
- (Note that this represents the minimum operating time, as it assumes full throttle for the whole time.)
Operating Safety
At motorzoo we are obsessed with operating safety. This is why we prefer LiFePo batteries over ternary Lithium-Ion (Li-Ion) mBatteries:
- LiFePo batteries are much safer to use than Li-Ion batteries, especially in an aquatic environment.
- We also prefer connections and cables with the highest water resistance rating (IP67).
