What is a series motor?
series motor in Electrical Engineering A series motor is a direct current motor that has two windings that are in series, with the same current flowing through each. The series motor provides high starting torque and is able to move very large shaft loads when it is first energized.
What is PMDC motor?
A Permanent Magnet DC motor (PMDC motor) is a type of DC motor that uses a permanent magnet to create the magnetic field required for the operation of a DC motor.
Which is the type of DC motor?
Types of DC Motors. There are 3 main types of DC motor that are available:- Series, Shunt and Compound. These terms relate to the type of connection of the field windings with respect to the armature circuit.
Is a brushless motor AC or DC?
Brushless DC motors are DC motors in the sense they are fed from a DC source. They use, however, an inverter (a type of power electronic converter) as an “electronic commutator” to provide an alternating current in accordance with the rotor position so that it can generate the torque.
What are the two main parts of DC motor?
DC motors include two key components: a stator and an armature. The stator is the stationary part of a motor, while the armature rotates. In a DC motor, the stator provides a rotating magnetic field that drives the armature to rotate.
What is the main advantage of a series motor?
The series motor has the highest starting torque for a given power rating. When the motor is overloaded, the speed drops and the torque increases. While delivering high torque during an overload, the series motor draws less current and power from the source compared to a shunt or compound DC motor.
What are the different types of DC series motors?
DC Series Motor Working and Its Applications There are two types of DC motors based on the construction such as self-excited, and separately excited. Similarly, self-excited motors classified into three types namely DC series motor, DC shunt motor, and DC compound motor.
What do you call a series wound DC motor?
In a series wound DC motor, the field winding is connected in series with the armature winding as shown in the figure. DC motors having both shunt and series field winding is known as Compound DC motor, as shown in the figure. The compound motor is further divided into:
How is the torque of a DC series motor calculated?
The DC series motor torque equation is, Torque= Flux* Armature current. T = If * Ia. Here If= Ia, then the equation will become. T= Ia^2. The DC series motor torque (T) can be proportional to the Ia^2 (square of the armature current).
What are the parameters of a series motor?
The per-unit speed and torque when the current is 0.5 p.u. The per-unit current and torque when the speed is 0.5 p.u. A d.c. series motor chopper drive has the following parameters: battery voltage = 96V, (Ra + Rf) = 0.1Ω, kv = 10mV/A-rad/s, chopper frequency = 125Hz.
What are the characteristics of a series motor?
Series motor characteristic. Series motors may be used for driving cranes as they can develop a large torque at low speeds. In all forms of electric traction, the road wheels are driven by series motors which are coupled to the wheels by gearing.
The DC series motor torque equation is, Torque= Flux* Armature current. T = If * Ia. Here If= Ia, then the equation will become. T= Ia^2. The DC series motor torque (T) can be proportional to the Ia^2 (square of the armature current).
Which is the series resistance of a DC motor?
R se is the series coil resistance and R a is the armature resistance. This is the basic voltage equation of a series wound DC motor. Another interesting fact about the DC series motor worth noting is that, the field flux like in the case of any other DC motor is proportional to field current.
How are the windings of a DC series motor connected?
The circuit diagram corresponding to the DC series motor, the field, and armature winding are connected in series is depicted. The equivalent circuit corresponding to this motor is shown in the figure below.
