Design the motor for your application

You can use these pre-set formulas to quickly and accurately determine if your motor requirements match well with MET’s DC Motors.

These are some of the standard voltage ratings for motors that we manufacture. Please select the voltage closest to that which you have available in your application:

12 Volts     24 Volts     36 Volts     48 Volts     90 Volts

Solar Powered Motors

MET Motors congratulates you on showing an interest in Solar Powered Motors.

Solar Power is the third most important renewable energy source in the world today. We at Minnesota Electric Technology are proud to have provided Solar Powered Motors to customers in this industry for many years.

Solar power, in addition to being a clean energy technology, is also considered “inherently elegant”. This means that the conversion from sunlight to electricity takes place without any moving parts or any environmental emissions throughout the process. The Solar Power Motor then runs off of this electrical source.

All of the Solar Powered Motors that we manufacture are custom designed for each customer’s application. We then sell that specific design only to the original customer. Our Solar Powered DC Motors have all been manufactured in our plant in Winnebago, MN since 1969. If you have an application for a Solar DC Motor, just send us your specifications and we will be glad to send you a no obligation quote.

The output of our Solar Motor can range from fractional horsepower up to 2 HP. Our Solar Powered Motor physical dimension ranges from 3.3” in diameter up to 6.0” in diameter. The electrical source can be 12 volts or 24 volts, or any other voltage that your solar array will produce. Send us your questions and we will be glad to work with you on your design. For more information on solar power applications, please check out our blog.

Solar Water Pumps

MET the Problem Solvers – providing Made in the USA

A potential customer was having difficulty receiving motors on a consistent and reliable basis from their European vendor. MET Motors was able to duplicate the performance for their motor and deliver them locally.

Solar Powered Motors

There are two major kinds of DC solar power systems:

  • Directly powered DC
  • Indirectly powered DC

For directly powered systems the solar panels start to provide the Solar Power Motor with low power as the sun rises, increasing during the day, and dropping to zero at night. The motor performance parallels these voltage and current levels. This system is the least expensive option. Our MET Solar Power Motors can work well in some water pump and fan applications here.

With indirectly powered systems you configure a battery between the solar panels and the motor. This lets the Solar Panel Motor run when the sun is not shining, but this option requires a battery charge controller. This system allows our Solar Electric Motor to run consistently all of the time.

How can our team help you to design an efficient solar system?

  • What work (horsepower) do you need to do the job? Your pump or fan provider can help with these specifications.
  • What voltage battery (12 or 24 or other) do you want in the system? Does your application require a deep cycle battery?

Our engineers at MET Motors can work with you to determine the capacity of the battery and the solar array that would be needed to power the Solar Powered Motor to do this work. Your battery, battery control, and solar panel suppliers can then use this information to help you finish designing the entire system. Please give us a call 507-389-4906 at any step in this procedure so that we can help you.

Inverted to AC power systems are an alternative.

For inverted to AC power systems you need to add an inverter to change from the solar panel’s DC voltage to the AC power. Then you also need a transformer to increase the voltage in order to be able to use an AC motor. Both of these devices cause a loss of efficiency, in addition to the inherent lower efficiencies of AC motors. This may require a larger system with a greater power generation capacity. These systems are used in homes with AC appliances.
