The difference between Servo motor and DC motor are explained here considering factors like number of wires used either two wire or three wire system. The assembly system used, rotation of the motor whether it is continuous or not. The examples of both the motor. Difference Between Servo Motor and DC Motor in the tabulated …
A Multi Stack or m stack variable reluctance stepper motor is made up of m identical single stack variable reluctance motor. The rotor is mounted on the single shaft. The stator and rotor of the Multi Stack Variable motor have the same number of poles and hence, the same pole pitch. All the stator poles …
The word Hybrid means combination or mixture. The Hybrid Stepper Motor is a combination of the features of the Variable Reluctance Stepper Motor and Permanent Magnet Stepper Motor. In the center of the rotor, an axial permanent magnet is provided. It is magnetized to produce a pair of poles as North (N) and South (S) …
The principle of Variable Reluctance Stepper Motor is based on the property of the flux lines which capture the low reluctance path. The stator and the rotor of the motor are aligned in such a way that the magnetic reluctance is minimum. There are two types of the Variable Reluctance Stepper Motor. They are as …
The Torque pulse rate Characteristics of a Stepper Motor gives the variation of an electromagnetic torque as a function of stepping rate in pulse per second (PPS). There are two characteristic curves 1 and 2 shown in the figure below. Curve one is denoted by a blue colour line is known as the Pull-in torque. It shows …
The Permanent Magnet Stepper Motor has a stator construction similar to that of the single stack variable reluctance motor. The rotor consists of permanent magnet poles of high retentivity steel and is cylindrical in shape. The concentrating windings on diametrically opposite poles are connected in series to form a two phase winding on the stator. …
A Linear Induction Motor (LIM) is an advanced version of rotary induction motor which gives a linear translational motion instead of the rotational motion. The stator is cut axially and spread out flat. In this type of motor, the stator and rotor are called primary and secondary respectively. The secondary of the linear induction motor …
As we have already seen What is a Servo Motor? In the previous article. Here I am going to discuss the Two Phase and Three Phase AC Servo motor. The stator of the Two Phase AC Servo Motor has the two distributed windings which are displaced from each other by 90 degrees electrical. One winding …
A Printed Circuit Board or a Disc Armature motor consists of a rotor disc made of non-magnetic and non-conducting material. The armature winding and the commutator are printed with copper on both the sides of the disc. The disc armature is placed between two sets of permanent magnets mounted on the ferromagnetic plates. Brushes are …
Servo Motor are also called Control motors. They are used in feedback control systems as output actuators and does not use for continuous energy conversion. The principle of the Servomotor is similar to that of the other electromagnetic motor, but the construction and the operation are different. Their power rating varies from a fraction of …
