Vyper 120A DC Motor Controller

[schwarzbraunbaer4711]

[font=Arial][size=2]Hello I am new in this forum, and I am not a Robot or electronic specialist![/size][/font]
[font=Arial][size=2]Pls help, excuse my poore englisch, I am from Germany![/size][/font]
[font=Arial][/font]
[font=Arial][size=2]I want to create a bow thruster on a boat (mo RC modell, a real one) with brushed 12 Volt motor 1400 Watt (= 117 Amps). The system allready exists and it is a industrial product.[/size][/font]
[font=Arial][/font]
[font=Arial][size=2]Now my question: Is the [highlight=#ffffff]Vyper 120A DC Motor Controller the right one?[/highlight][/size][/font]

The “bow thruster” must be controlled via a Joystick (potentiometer) an when I turn the joystick left, the motor must (speed controlled) turn for example clockwise, in the middle position of the joystick the motor mustn´t turn and when I turn it to the other side , the motor must turn counterclockwise.

What potentiometer (Size of Ohm) will be the right one?

When I see the cable conectors on the controler I am not shure if the size is big enough, in the moment the motor is conectet with 35 mm² cables

Thank you for the will of helping me!

Hi,

Welcome to RobotShop’s forum.
The Vyper 120A DC Motor Controller could be a good choice for your application. It can provide up to 120A continuously. Therefore, it should be sufficient if your motor consumes 117Amps under nominal load.
It can be controlled in Potentiometer Mode in both Forward or Forward/Reverse configuration. You would need to control it in Forward/Reverse for your application.
Here is the description of this mode from the User Manual :

Forward or Forward/Reverse ­ In Pot mode Setting the #3 switch to ON activates Forward and Reverse mode ­ OFF activates Forward Only Mode. In Forward/Reverse mode the pot control will be off in the center position with power to the motor increasing in either the forward or reverse direction as the pot is moved away from the center position. In Forward Only mode the power to the load will be off at one extreme of the pot travel and power will increase in only one direction as the pot is moved to the other extreme. This is similar to a scooter or car throttle action and is used where reversing voltage to the load is not needed.

You can use for example this 2 Axis Joystick or this 2 Axis Joystick GIM-01. Here is the Wiring Diagram for the Vyper 120A with the potentiometer.

You have to be sure that your motor doesn’t consume more than 120Amps under load otherwise you can damage the Vyper controller. You can find this information in your motor’s datasheet.
