Selecting the Motor and Driver Selecting the proper motor and driver to meet a specific application needs motor torque and speed. Generally we will calculate torque of the motor first based on torque value we have to calculate speed of motor. 4 steps for calculate torque : 1.Determine the motion profile and calculate acceleration ,deceleration ,maximum velocity required to make the desired move . 2.select the mechanical drive mechanism to be used and calculated inertia ,friction and load torque using formulas provided in this document. ex.1.Lead screw drive 2.Ball screw 3.Belt drive 4.direct drive 5.gear drive loads 3.Determine required motor torque for the specific application . 4.select proper motor and driver based on their speed -torque characteristics .
