Clark voltage booster
« on: April 18, 2017, 03:42:31 PM »
Gday Mark
I was wondering if the Clarke dc to dc voltage booster can be utilized to momentarily increase the speed of a 3-12v dc motor by increasing the voltage from 7.2v to 12v.
The motor is 10mmx12mm with a free run current of approx 70 ma and a stall current of approx 1600 ma.
If this board wont work do you have any ideas as to what I could use.
I don't have room to fit a servo but perhaps I could pull a servo apart and use the servo's board to drive the motor.
Any suggestions would be appreciated

Hey Biff,
Good to hear from ya.
What is the DC Motor used for (rotation/elevation etc.)?
While i haven't heard of this set up before using the Clark unit- it could be used depending on the application.

It really depends on what you mean by Momentarily Increase.
Cheers

Basically I want to convert a dc3-12v geared motor with a m3x80mm shaft(see piccy) into a linear sevo to create a recoil system for a 15cm german howitzer.
I could just hang a servo on the side of the gun but I want to hide the recoil system in the gun cradle which is 13x12x185 mm thus the use of the micro geared motor.
The geared motors operate at various speeds that is controlled by an increase or decrease of voltage to the motor. The battery is standard 7.2v and to achieve max speed I have to momentarily boost the voltage to 12v to obtain correct speed for recoil length and return.
The other alternative is to make a 12v battery pack and step the voltage down to operate the rest of the system which is on 7.2v.
I have the room to fit a 12v pack and can make a custom 12v battery pack which may be the easiest way to go.

Sounds interesting mate. It should be ok to use.
If the motor that is to be attached to the linear servo is the only motor you need 12v to, then i would step up the voltage for that one application.

Well you never know till you have a go so I have placed an order for a couple of units and will run some tests to see how they go.
If the units arent suitable for the recoil system at least I will have a couple of loud tanks lolol
will let you know the results
Happy tankin  ;D

I contacted Clark re their voltage booster and they supplied the following information
The input is 3 to 32 volts, out put is 5 to 35 volts with 50 watts max.
I have no idea what the amperage is but I guess a test run on a motor will sort that out.
Happy tankin
