What are the factors that influence the speed of the direct-current shunt motor with increasing load?
.The magnitude of the voltage and current of both the armature and shunt field coil.
To decrease the speed when the load is increasing then increase the shunt field current while decreasing the armature voltage or current.
To increase the speed while the load is increasing then increase the armature current while decreasing the shunt field current. The decreasing and increasing of these currents and voltages can be done by connecting a variable resistor in series or parallel with each of the armature and/or shunt field coil.
What else can I help you with?
How will the speed and the slip of the motor change with increasing load in star wye and delta connection?
the speed decrease if increasing load..in star connection the speed lower
How do you reduce kwh by caacitor using?
To reduce kWh by capacitor is when a motor is put in. The terminal voltage is reducing and current is increasing it is connected parallel with the motor.
What is the effect of increasing number of poles on the speed of an induction motor?
As the number of poles (P) increases, the speed of an induction motor (N) decreases. As seen by the formula: N=(120*f)/P
Why use dc motor not stepper motor in robot?
DC motors use PWM (pulse width modulation), which can easily increase or decrease the power to the motor, thereby increasing or decreasing the motor speed by modulating the width of the pulse. Stepper motors have fixed frequencies, thereby having fixed motor speeds. As a result, the speed of the stepper motor cannot be controlled when the load is increased.
How can you increase the torque of an electric motor without increasing the speed?
keep the same winding configuration or number of poles increase the diameter of the rotor and stator
What factors influence the shape of an electric motor efficiency curve?
The shape of an electric motor efficiency curve is influenced by factors such as the motor design, operating conditions, and load characteristics. These factors can affect how efficiently the motor converts electrical energy into mechanical energy, resulting in variations in the efficiency curve.
What does the company Transco Motor Factors do?
The company Transco Motor Factors makes various types of engines for people who are intersted in buying them. Transco Motor Factors also donates to many charities.
What is the effect of increasing the length of the air gap in an induction motor?
The magnetic flux that couples the rotor to the stator will weaken significantly reducing the motor's torque.
Does the number of batteries affect the speed of a motor?
The number of batteries can affect the speed of a motor. Increasing the number of batteries can provide more power to the motor, potentially increasing its speed. However, there may be limitations based on the motor's design and the capacity of the batteries.
What does recruitment and frequency of stimulation affect?
Recruitment affects the number of motor units activated in a muscle, while frequency of stimulation affects the force generated by those motor units. Increasing recruitment leads to more muscle fibers being recruited, increasing force production, while increasing frequency of stimulation produces stronger muscle contractions by increasing the rate at which motor units are activated.
Use of a turbo in a car?
To increase power of the motor, by increasing airflow thru the motor(higher volumetric effiecency) when needed.
If you increase or decrease the frequency what effect on electrical machin?
If you're talking about an electric motor, increasing the frequency will increase the speed of rotation of the motor, and decreasing the frequency will decrease the speed of rotation of the motor. The other way of controlling a motor is to control the current; increasing the current increases speed, decreasing current decreases speed.
Increasing the number of active motor units is called?
Muscle recruitment
How do you build an electric motor with over 2000 RPM?
an electric motor can be build with over 2000 rpm,by increasing the supply frequency.
Why 3 phase induction motor never atteined sinkronas speed?
Induction motors run at sub synchronous speeds because the slip (difference between synchronous and actual speed) causes, or controls the electric field strength in the motor. As more load is put on the motor, the motor's speed decreases, increasing slip, and increasing the electric field strength.
How will the speed and the slip of the motor change with increasing load in star wye and delta connection?
the speed decrease if increasing load..in star connection the speed lower

To reduce kWh by capacitor is when a motor is put in. The terminal voltage is reducing and current is increasing it is connected parallel with the motor.
