Brushless Drive

ArduMower Brushless Drive

Coming soon, information about the 2021 announces new Brushless Drive for the ArduMower.

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.
