Brushless Drive
ArduMower Brushless Drive

Why brushless and what are the advantages?
A brushless motor offer several advantages over brushed DC motors. The main advantages are high torque to weight ratio / same power by smaler case design, more torque per watt / better energy efficiency / longer motor worktime per battery cycle , increased reliability, reduced noise, longer lifetime because of no brush and commutator erosion, and an overall reduction of maintenance and service cost.
The disadvantage is, a brushless motor and his driver are much more expensive than a brushed DC motor. But if you see the total cost over ArduMower live time, you will see an overall cost reduction abd a very fast return on investment, especially for large lawn area. The cost advantage will take place after 2-4 years (depends on loan area and mower usage), by end of life of the brushes and commutator of an DC Motor, where you have to replace the DC Motor by a new one. So for high usage on large areas, you will amortize the higher invest within 2 or 3 years and save a lot of money.
Out of this pro and cons you can select the right drive solution for your ArduMower.
DC motor drive : small loan area, less working hours of the ArduMower per week.
Brushless drive: large loan areas and 5-7 days / week usage of the ArduMower. Longer working period per battery charging cycle.
ArduMower drive concept
Since 2021, the ArduMower project supports a wide scale of drive options. From the powerful and cost efficient DC motor over the special AduMover Brushless Drive for larg power drives up to high power drive with commercial brushless controllers. The DC and the AduMover Brushless Drive are supported by the community and the parts will be availably in the online shop [1]. The high power drive is very special and needs some individual adaptions. If you are interested please get in contact with BerndS via ArduMower Form.
In this part we will not cover the DC motor drive. We will focus on the AduMover Brushless Drive and how to handle.
