Choosing the perfect trolling motor we need to consider some important factors, like knowing the characteristics of the load, having an idea to necessary Kilowatts, Start, duty cycle and hypoxia engine.

How to choose trolling motor & the right trolling motor battery

Loads that can withstand working engines fall into three general categories: constant torque, torque changes abruptly, and the torque change over time.

CONSTANT PAR: The conveyor belts of materials, extruders, positive displacement pumps operate at relatively stable levels par.Calcular engine size for these applications is simple once the torque (or horsepower) for the application is known.

PAR WITH abrupt change: The need for load lifts, compactors, punch presses, saws, conveyors and change abruptly from strength to strength in a short period of time, often in a split second. The most critical aspect for the selection of an engine in these cases is to choose one whose curve speed-torque exceeds the load torque curve.

COUPLE WITH TIME CHANGE: Loads of centrifugal pumps, fans, blowers and similar equipment tend to be variable in time. In choosing a trolling motor for these conditions, consider the highest point continuous load, which normally occurs at the highest speed.

Having an idea to necessary Kilowatts

The golden rule to calculate the trolling motor power KW is: select only what you need and avoid the temptation to implanter more or better size.

Calculating the required power of the following formula:

Power (KW) = Torque (Nm) x speed (rpm)

Start

Another consideration is inertia, particularly during startup. Each load represents a value of inertia, but punching machines, ball mills, crushers, reducing moving large rolls, and certain types of pumps require high starting torque due to the mass of the rotating elements.

Engines for these applications need special qualifications so that the temperature increase at the start over limit allowable temperature. A properly sized engine must be able to rotate the load of a neutral (locked rotor torque), pull it up to the operating speed (par pull-up), and then maintain the speed of operation. The engines are rated as one of four “types of construction” for its ability to withstand the heat of the boot and pull up.

In ascending order the ability for starting inertia loads, NEMA designates this as type A model, B, C, and D. Type B is the industry standard and is a good choice for most commercial and industrial applications .

Set duty cycle

The duty cycle is the charge that a trolling motor must handle during the period when it starts, runs and stops.

Continuous operation is far simpler and more efficient application. The work cycle begins with the start, and after long periods of continuous operation, where the heat in the engine can be stabilized as running due to ventilation. A continuous duty motor can safely operate at or near its rated capacity because the temperature has a chance to stabilize.

Intermittent operation is more complicated. The life of commercial aircraft is measured by its number of landings; in the same way, the life of a trolling motor is proportional to the number of starts made. Frequent starting shorten life because the input current at startup quickly heats the driver.

Because of this heat engines have a limited number of starts and stops that can be done in an hour.

The last consideration, hypoxia engine

If the engine goes to work at heights that are substantially higher above the sea, you will not be able to function at its factor full service because, at altitude, the air is less dense and does not cool as well. This consideration must have it for applications in high altitudes.

Trolling motor battery

A suitable marine battery is one of the most important components for the trolling motor to function properly. It helps to start the engine keeps running and electronic components. It also lets you charge your phone and play your music, even with the engine off.

But car batteries gradually lose power over time and cold weather affects a lot.

You should check the battery of your car at a local dealership. If you need a new trolling motor battery, we show you what you need to know to get the right.

What you need to know to choose a new trolling motor battery

When choosing a perfect trolling motor battery, you should consider three important factors: size, amperes for cold starting and reserve capacity. Here we provide more information to help you choose the right trolling motor battery for your trolling motor.

Battery size

The size includes the length, width and height of the battery. Some vehicles batteries support more than one size, so you should consult the owner’s manual to find out what size battery is appropriate.

Cold start Amperes (CCA)

The CCA is a very important indicator battery performance. They are based on how well a new battery will provide enough power for 30 seconds at zero degrees Fahrenheit. The higher the number, the better.

The number of CCA of the battery should match the number of CCA owner’s manual, or the CCA of the original vehicle battery. If you live somewhere cold weather, maybe a CCA rating slightly higher beneficial to the cold start performance of your vehicle.

Note that some marine batteries used numbers amperes for hot start (HCA), amperes to boot (CA) or amps for starting marine use (MCA). Numbers HCA, CA or MCA may seem higher than the number of CCA, this is because the tests are taken at 32 degrees and 80 degrees Fahrenheit, and thus are not equal to the CCA. Choose a battery according to the number of CCA.

Reserve Capacity (RC)

The reserve capacity is another important performance indicator. It measures how many minutes the battery can provide power before falling below the minimum voltage level.

As for the RC, the higher the number, the better. This is an important thing to keep in mind if you will use electrical equipment in your vehicle with the engine off factor.

Date Code Battery

Most batteries have a date code that shows when manufactured. The date codes are on a label or can be recorded on the same battery.

The original marine battery in your Ford, the first two characters of the code without a letter and a number. The letter is a month: A equals January, B for February, etc. The number is the last digit of the year of manufacture. For example, a code starting with A9 mean that the battery was manufactured in January 2009.

When you buy a new marine battery, be sure to ask the seller for the battery size you need. A battery that has been on sale for an extended period can lose some charge and not have a good performance.

Warranty

Read the battery warranty. See also how long the free replacement period and if you have any proportional coverage after that point.
