Stepper motors are motion systems allowing to have a high positioning precision.With their high power already at low speed, their stall torque and the possibility to divide the steps in microsteps, stepper motors can provide direct and precise motions in a small volume.Permanent magnet and hybrid technologies are used to provide a full range of solutions.The absence of mechanical commutation gives to these motors a long life time which is usually given by the sleeves according to the load applied on the shaft.
A brushless DC motor (BLDC) is a synchronous electric motor which is powered by direct-current electricity (DC) and which has an electronically controlled commutation system, instead of a mechanical commutation system based on brushes. In such motors, current and torque, voltage and rpm are linearly related.
Often referred to as a “tin can” or“ can stack” motor the permanent magnet step motor is a low cost and low resolution type motor with typical step angles of 7.5 to 15°
(48 – 24steps/revolution) PM motors as the name implies have permanent magnets added to the motor structure.
The rotor no longer has teeth as with the VR motor. Instead the rotor is magnetized with alternating north and south poles situated in a straight line parallel to the rotor shaft. These magnetized rotor poles provide an increased magnetic flux intensity and because of this the PM motor exhibits improved torque characteristics when compared with the VR type.
A Servo Motor is defined as an automatic device that uses an error-correction routine to correct its motion. The term servo can be applied to systems other than a Servo Motor; systems that use a feedback mechanism such as an encoder or other feedback device to control the motion parameters. Typically when the term servo is used it applies to a 'Servo Motor' but is also used as a general control term, meaning that a feedback loop is used to position an item.
