LSK D.C. motors General information A6 - Standard formulae used in electrical engineering A6.1 - MECHANICAL FORMULAE Title Definitions / Notes A force F is the product of a mass m multiplied by an acceleration γ Torque (moment) The torque (moment) M of a force in relation to an axis is the product of that force multiplied by the distance r of the point of application of F in relation to the axis. Power P is the quantity of work yielded per unit of time Acceleration time ω = 2π N/60 where N is the speed of rotation in min–1 (rpm) J is the moment of inertia of the system Ma is the moment of...
