please clarify, which company and model number
An SCR chip is commonly used to control the speed of a motor. The speed is controlled using an AC circuit and phase angles.
the normal speed of motor can be set by varing field current before using the turn
an electornic speed controller. It controls the speed of the motor using high power transistors.
By using your brain
The speed of the motor depends on load, voltage and current. The speed can be maintain by using a method called Pulse code modulation (PWM). By changing (modulating) the width of the pulse applied to the DC motor we can increase or decrease the amount of power provided to the motor, there by increasing or decreasing the motor speed. mean we have to just change the duty cycle of modulating output.
It is depends on the application. If we need any variable speed in motor, dc motor will be better choice.
No. If you attempt to reduce the voltage to a cap start motor by using a rheostat, you can destroy the motor.
By using the star- delta starting methodBy using variable rhoestatsBy using auto transformers
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.

This motor is able to work from the battery. The speed is less complicated to use and you do not need much voltage.
The DC motor speed control has a scope of four speeds. The control speeds include; high, medium, low, and off.
The maximum current of the pole changing motor when running at low speed and high speed depends on a few different things. The average when begin at low speed and using high speed is 1800 RPM points.
