well, you either have to program the operating frequency crystal to a better remote control, (if you are using a remote control,get
remote control which can control the speed) or, try using a more powerful or less powerful battery to increase or decrease the speed.

How does bridge rectifier control a DC motor?
give answer how to control the speed of dc motor using bridge rectifier ? ANSWER: A bridge rectifier by itself does not control anything it merely convert AC into DC. the controlling is done by other means SCR TRIACS AND SERVO loop
Can a DC series motor with speed control be connected on AC supply?
A dc series motor with speed control can be connected on ac supply because dc machines are totally reversible.
Why ac drive convert ac voltage in dc?
It is done to control the speed of the motor.
Speed control of motor using SCR?
An SCR chip is commonly used to control the speed of a motor. The speed is controlled using an AC circuit and phase angles.
What is the importance of speed control of DC motor in industrial applications?
The speed control of the DC motor is important because its speed can be changed over a wide variety of simple methods which is not possible in an AC motor.
What is ac drive and how it works?
An AC Drive used for a speed control of a motor by using vary frequency.
Can you use a rheostat on ac motor?
Yes you can use a rheostat to control the speed of an ac motor as long as it is correctly sized (power). A better way would be to use a triac control.
How does an ac drive variable speed drive operate to control speed?
Answer #1 It varies the frequency fed to a synchronous AC motor. As the frequency changes, so does the motor speed. Answer #2 The formula for calculating speed is: (120 X motor supply frequency) / number of poles 120 is a fixed number, so is the number of poles for a given motor, hence the only variable is the motor supply frequency. AC drives vary the motor supply frequency in turn achieving speed control.
How do you control the speed on an ac motor?
the speed of ac motor can be controlled by controlling the synchronous speed (Ns=120f/p). and synchronous speed can be varried or controlled by changing frequency or by changing poles. but practicaly pole can not be changed. but we can change the frequency. the frequency can be VFD (Variable frequency Drives). so the speed of ac motor can be chaged or controlled by VFD.
What is the AC drive?
An AC drive is a device that converts AC power into a desired frequency to allow for AC motor speed control. This term is commonly used in engineering.
Electronic component used to control speed of a motor?
In industrial, there is a device called variable frequency drive (allso frequency inverter, ac drive) to control the motor speed by adjusting output frequency.
How do you you control the speed of a dc motor?
A Potentiometer, an adjustable resistor, is connected between the power source and the motor. An AC motor would use a Rheostat .
