  • A motor converts supplied electrical energy into mechanical energy. Various types of motors are in common use. Among these, brushless DC motors (BLDC) feature high efficiency and excellent controllability, and are widely used in many applications. The BLDC motor has power-saving advantages relative to other motor types.

  • Jul 12, 2020 · AC series motor or the universal motor is an electric motor that operates in either Ac or Dc power at the same speed and output. Also, Ac series motor is a modified Dc series motor. What does this mean; it means that we modify the DC series motor to be able to work in AC single-phase supply. This modification includes the following as:

Aug 22, 2020 · Answer 4. Universal motor. Explanation: We use universal motors in mixer grinders. Universal motors can run both on a.c. and d.c. The universal motor works on the same principle that DC series motor works. DC series motor has the characteristics of operating at high-speed when there is no load and operating at low-speed when the load is applied.
  • Encoder Working Principle Theory What does the word encoder mean? The encoder is an electromechanical device that can measure displacement. Encoders are normally digital displacement transducers, consisting of a mechanical element and a sensing head, typically of optical type. The mechanical element can be a disc (for rotary

  • When the DC supply is given to the motor, a direct current passes through brushes, commutator and armature winding. When it passes through commutator, it converts DC into AC. Therefore the group of conductors under the influence of N – pole and S - pole carry currents in the reverse direction.

  • Nov 06, 2018 · 1. DC servo motor : The basic operating principle of DC motor is the same as other electromagnetic motors. The design, construction, and the modes of operation are different. The rotors of this kind of motor are designed with long rotor length and smaller diameters. Their size is larger than that of conventional motors of same power ratings.

Servo motors is actually the dc motor and all dc motors work on the principle of Fleming s left hand rule. This rule is used for determining the direction of force which act on the DC motor armature conductor. This rule tells us if we extend our left hand,index finger, middle finger and thumb in such a way that shown in figure 3
