For any dc shunt motor the speed is directly proportional to the armature voltage. hence if you vary the armature voltage by any means( using thyristor ) or static converters using conventional method( ward Leonardo system) surely you can increase or decrease the speed of the shunt motor.

Which DC motor is constant speed motor?
Dc shunt motor is constant speed motor.Its speed is constant with armature current.This shunt motor is used in paper mills and drilling machines
What is constant speed DC motor?
Dc shunt motor is constant speed motor.Its speed is constant with armature current.This shunt motor is used in paper mills and drilling machines
Why speed control of DC shunt motor is necessary?
The total voltage of the batteries or DC power source connected to a shunt motor affects how first it moves. Increasing the DC voltage will make the shunt motor run faster.
What are industrial applications of DC shunt motors?
Dc shunt motor is a constant flux and constant speed motor . So that it is used in centrifugal pumps ,machine tools ,blowers and fans etc.
Why do you control the speed of constant speed dc shunt motor?
no it controls your anus
What is DC shunt motor?
A shunt DC motor connects the armature and field windings in parallel or shunt with a common D.C. power source. This type of motor has good speed regulation even as the load varies, but does not have the starting torque of a series DC motor
Why is the speed of dc shunt motor practically constant under the normal condition?
The speed of dc shunt motor is practically constant under the normal condition because the field flux is constant.
How do you underspeed shunt motor?
To underspeed a shunt motor, you can reduce the armature voltage by using a variable resistor or rheostat in series with the armature circuit. This decreases the current flowing through the armature, thereby reducing the motor's speed. Additionally, you can also adjust the field current, as a decrease in field strength will increase the motor's speed, but this must be done carefully to prevent motor instability. Always ensure to monitor the motor to avoid overheating or damage.
What will happen to a shunt motor if a shunt field coil opens while the motor is running under light load?
Motor will rotate at very high speed leading to destructionAnswer from Kinindia.com
If the speed of the dc shunt motor falls due to loading what will be the effect?
on adding load on a dc shunt motor, the amount of current and torque will increase. but terminal voltage will decrease
Which parameters speed of DC shunt motor depend?
base speed is the speed with full voltage on the shunt this speed is mostly from the number of poles , single pole fastest max speed is when you weaken the shunt the limit is the amount of power the armature can take and thing like bearings an strength of the reinforcement of the windings
What is function of dc motor in lift?
Shunt motor is used. For constant speed ,torque will high when load is increased
