We have several type of DC motor PWM controllers! Simple forward or reversible version.
Up to 300A and 200V with programmable USART and other useful functions and more.. Because of some missunderstandings for those customers who does not need the programing registers and the serial communication they dont have to learn and deal with the programing! The controller is fully working without doing any programing.In the datasheet you will find information about the programing but telling you again that is not important to you if you just want to use a simple potentiometer or throttle controlling your motor. You just need to choose the controll mode with the red DIP switch 1-2 on the board. The controller's registers are optional for those users who need this function for their application. Use this controller for any brushes motor! Like: trolley, outboard, electric bicycle or more... Advantages against other motor controllers. True heavy load 5x15mm copper trails can handle very high peak currents and 350A continuous current.
TTL Serial RX/TX intarface with full access of controll registers and much more usefull adjustable parameters. Advanced 3 x 2 layers PCB layout technik. High speed 32bit Cortex processor. Connection with high current M6 screws. Built with ultra low resistance MOSFETs.Adjustable 4 operation modes: 1. Magnetic hall throttle (with 0.5-4,5V output) 3. Direct PWM input (0-95%) 4. RC PWM input 1,5ms +/-1ms. 2 quadrant operation (drive CW and regenerative brake CW). Low warming and capable to accept heatsink.
Universal 0-5V speed controller input. You don't have to use the potentiometer to controll the speed.You can use PLC output or any analog signal or PWM signap from uPC or RC receiver PWM signal. Regenerative braking (you can brake the motor and get back all the kinetic energy into the battery) For the highest safety the regenerative braking never. Normal current continuous limit is adjustable between 0-350A. Switchable peak current ON or normal strict current limit. Peak current 500A for 5 seconds. Universal supply voltage between 22-200V DC. Dimensions: 320 x 155 x 50 mm. Note: For the maximum power you have to add extra heatsink to the aluminium block. The aluminium block is predilled with M5 holes.
You can choose between 6 operation modes with the red DIP switch on the PCB board. Normal potentiometer mode 0-5V 0-97% output voltage.Magnetic hall throttle mode (0.5-4,5V input) or programable input voltage like 1-3V or anything you want. Simple PWM signal (0-95%) from arduino or a RC receiver. RC receiver PWM input 1,5ms +/-1ms. RS232 controll with simple commands recommended for beginner programmers for example Arduino. RS485 advanced controll for precise industrial controll. With the optically isolated connection and CRC protected communication you can communicate with the device and get access for the all controll registers. Adjustable and saveable parameters with TTL serial read/write commands for simple Arduino protocoll for beginners and advanced protocoll for industrial communication. Turn ON/OFF minimum and turn ON/OFF maximum voltage levels for example turn off the unit at low battery voltage. Potentiometer input voltage (you can use this input for an analoge measurement input if you are controlling the speed with RS232/485 commands). Input frequency on PWM input. Input duty on PWM input. I x R compensation (this if for speed regulation compensation the load drop voltage). Supply compensation (maximum speed limit) this can be very usefull in more cases. As you give a maximum reference voltage (maximum RPM) what the output can be with the maximum gas setting. This value becomes a reference voltage and archive perfect supply voltage compensation. This means if your supply voltage drops of raise your motor PRM remains the same. Using the supply compensation and the I x R compensation together you can archive perfect speed regulation without any closed loop feedback and no tachogenerator is needed. Adjustable RS485 address controlling more controllers on one line.
For more information and how to use the serial communication please read the datasheet with the controll registers. They are great until you put a large load to theirs output.
That controllers don't have supply filtering what is very important! Without it the most of the chinese controller regularly burning down.They haven't got proper freewheele diode against the motor inductive current! The most of them don't have any current limit function which is very important by a motor. This unit is a current limited speed controller for any brushed DC motor with great LOW ESR capacitor supply filtering and a syncgronous switching freewheel diodes! How can you controll the motor speed with this controller? With the current limit potentiometer you can very fine adjust the current what the motor can maximum consumes. For example, you have 2000W 24V DC motor. Your motor nominal current is 83A.
Than you adjust the current limit to 80A. After them your motor and PWM driver is fully protected against the burning down and over load. Additional protection is the temperature protection.The controller measure the temperature of heatsink. If that exceed the maximum than the controller will shutting down. You can easily control the motor speed between 0-95% with the motor speed controller potentiometer which is connected to the potentiometer terminal.
Of course if you have a throttle you can use it ot if you have a special project and you want to controll the unit with your PWM signal which comes from your uPC unit you aslo can do taht. If you have any question special request or something, please feel free to contact, we are electrical engineers there isn't problem what can't solve. We will see what can we do.If you need more pieces please contact I can give you discount! Worldwide: mainly 8-12 days (avrerage).
