Motors and drives are just like a twin, motor is in charge of energy gerneartion, and drives is in charge of control. If therer is only motor, there won't can make any movement. If there is only drives, there is nothing to control.
Electric motor working principle is Electro-Magnetism. The stepper motor design converts electrical power into mechanical power. It includes a rotor which is made with a permanent magnet whereas a stator is with electromagnets. When power supply in on, the magnetic field will be surrounded within the stator. The rotor will rotate with the magnetic field of stator.
The linear slides uses a precision lead screw assembly mechanism to provide controlled positioning along the axis of a robust aluminum linear slide, The carriage is a small platform with thin stainless ball bearing guides that glide within this specially configured extrusion. The linear slides are capable of accurate and precise straight-line motion and can handles high moments.
