To better answer questions about performance and reliability when it comes to anchor winches one should really consider the many different types of anchor winch motors.
Electric 12 or 24 volt Series Wound Motor
Electric 12 or 24 volt Permanent Magnet Motor
Which Type of Electric Anchor Winch Motor is Best ? There are two basic types of DC motors used for electric anchor winches. The first type is a Series Wound Motor (Wound stator with electromagnets connected in series),and the second type is a Permanent Magnet Motor (Permanent magnet stator).
As you may already know, there are two electrical elements of a DC motor, the field windings and the armature. The armature windings are made up of current carrying conductors that terminate at a commutator. DC voltage is applied to the armature windings through carbon brushes which ride on the commutator. In DC motors used for industrial applications the stator is an electromagnet. However, in smaller , less powerful DC motors, permanent magnets can be used for the stator.
Let’s see the basics of each type as well as their advantages and disadvantages.
1. Series Wound Anchor Winch Motors – such as those used on E-Z Anchor Pullers are designed for heavy duty anchor winching and have MORE Horse Power. In a series DC motor the field is connected in series with the armature. The field is wound with a few turns of large wire because it must carry the full armature current. A characteristic of series motors is the motor develops a large amount of starting torque. They are powerful and efficient at high speeds.
With a series wound motor the amp draw will stay the same throughout the pull. Keep in mind that anchor winches with series wound motors tend to cost more than anchor winches with permanent magnet motors. A permanent magnet motor uses less amp draw than a series wound motor; however, as the permanent magnet motor heats up, the power will drop as the amp draw increases.
2. Permanent Magnet Anchor Winch Motors - such as those used on Australian & other Imported anchor winches are designed for light to medium duty anchor winching and have LESS Horse Power. A disadvantage of permanent magnet DC motors is they are limited to the amount of load they can drive. These motors can be found on low horsepower applications. Another disadvantage is that torque is usually limited to 150% of rated torque to prevent demagnetization of the permanent magnets.
The permanent magnet motor uses a magnet to supply field flux. Permanent magnet DC motors have good speed regulation and moderate starting torque capability. They place less of a drain on your battery than a series wound motor, but they also generate more heat than series wound, so there’s a greater chance that your anchor winch motor will overheat. You can compensate for this tendency to overheat by taking frequent breaks during the anchor winching process to let the motor cool down. The heavier the load and the longer the pull, the more breaks you’ll need to take.
A Note About Horsepower - The higher the horsepower, the more torque and power that the anchor winch motor will have. Horsepower directly affects line speed and pulling power.
For anchor winches, light to medium duty is generally regarded as boats up to 5,500 pounds and/or 25 feet long. For heavy boats up to 25,000 + pounds and/or 60 feet long, series wound motors are your best bet. They handle heavy loads and longer pulls with ease.
Electric Anchor Winch Motor Vs. Hydraulic Anchor Winch Motor
When it comes to picking an E-Z Anchor Puller for your boat, you have a choice between an electric anchor winch motor and a hydraulic anchor winch motor. Each has advantages, each disadvantages, and both are capable of pulling your anchor weight. The factors that go into your final decision go beyond that simple qualification, however, and your choice will be limited by the type of boat you will use the anchor winch on, how the boat’s systems are set up and how much time and effort you’re willing to put in to have the anchor winch of your dreams.
1. Basic Operations
The electric anchor winch is operated by a 12v or 24v battery on the boat that is connected to an electric motor & solenoids on the anchor winch with heavy gauge marine battery cables and circuit breaker. It’s controlled by an switch at the boat’s helm which is wired to solenoids that control the direction of the motor. To raise or lower an anchor, you push the button, the anchor winch motor turns the spool and raises or lowers the anchor.
A hydraulic anchor winch is operated by a hydraulic pump on the boat and hydraulic gear motor on the anchor winch. The hydraulic fluid flows from the boat’s hydraulic reservoir to the motor through the hoses and controlled by a globe valve located at the helm. To raise or lower an anchor, turn the valve slowly in the desired direction, until the spool turns at the desired speed. To stop the anchor winch, close the valve. The rotation speed of the spool that winds up the rope and chain is controlled by opening or closing the control valve.
2. System Requirements
An electric anchor winch must be permanently tied to the boat’s electrical panel, on a dedicated circuit.
A hydraulic anchor winch requires that the boat have a functional hydraulic system installed.
3. Simplicity of Installation
Installing an electric winch consists of mounting the winch, wiring the winch to the battery and installing the control switch. It should be on a separate circuit in your boat’s electrical panel to avoid “brownouts” in other electrical equipment or lighting.
The hydraulic anchor winch requires the presence of a hydraulic system. If a system is already present on your boat, then installation is as simple as mounting the anchor winch inside a deck dam (a containment area on the deck to contain fuel and oil spills) and adding a globe valve and hoses. If your vessel is not equipped with a hydraulic system, you must install one before using a hydraulic anchor winch.
