how much power is needed to move a linear axis

For linear acceleration of a mass, the power required will depend on how quickly you want to accelerate it. This is because the Kinetic Energy formula is $E_k = \frac{1}{2} m v^2$. Note the v squared. ...

Measuring shaft torque of a small motor

For future reference, If you want to measure the shaft torque of a small motor, just couple it with a DC generator (basically a DC motor) and then short circuit the terminals. The power will dissipate ...
