The Application of Motor Speed Controller

Someone needs a control system for controlling a DC 12v engine. He seeks to control the speed of rotation depending on the voltage applied.
We recommend 2 channel motor speed adjustable remote controller—S2PFS-DC12 and CV-6-2. By comparison with other motor remote controller, this controller S2PFS-DC can control speed of motor rotation. It won’t depend on the voltage applied because two speed control knobs on the receiver are to adjust the speed of two motors separately.  You can control two engines by one remote controller simultaneously. Maximum working current is 10A for each channel.

You may be wondering how it works. Let’s show you how to control speed of two motor rotations.
1 x 2 channel dc remote control receiver (S2PFS-DC12)
1 x 6-button remote transmitter (CV-6-2)
1 x dc12v power adapters
2 x dc motors

Here comes the wiring.
Motor 1 is supposed to be connected to terminals A1&A2 at receiver. Motor 2 is supposed to be connected to terminals B1&B2 at receiver.

Speed Adjustable Operation
Besides ordinary starting and stopping operation, rotation for forward and reverse by transmitter, we mainly show that twist two knobs on the receiver to adjust the speed of rotation.
Knob 1 controls motor 1; Knob 2 controls motor 2.
For motor 2, twist the knob 2 anti-clockwise, the speed will be faster; twist the knob 2 clockwise, the speed will be slower.

For motor 1, twist the knob 1 clockwise, the speed will be slower; twist the knob 1 anti-clockwise, the speed will be faster.
