the loading arrangement used in normal electrical machines is brake drum - spring balance arrangement. This is used to calculate the torque and output power.
the formula for torque is 9.81*(diffference between the spring balance) * radius of brake drum.
thee output power obtained is 2*π*motor speed*torque obtained

What is meant by bressless DC motor?
I've not heard the term "bressless" - I think you mean "Brushless" - which is a DC Motor that does not use the usual commutator/brush arrangement. For a great answer to this question, see the Wikipedia article in the related links section.
