Die Pololu Simple Motor Controller sind vielfältige, universelle Motorcontroller für DC Motoren. Er besitzt einen Arbeitsbereich von 5.5 bis 40V / 15A. Mit einer Vielzahl an unterstützten Interfaces, sowie einer Anzahl von konfigurierbaren Einstellungen, ist der Controller ideal um DC Motoren und kann so in verschiedenste Projekte eingesetzt werden. Durch die freien Konfigurationsmöglichkeiten des Controllers (für Windows 8, 7, Vista, Windows XP und Linux) wird der Aufbau / die Installation verschiedener Geräte vereinfacht und ermöglicht System interne Tests oder Prüfungen via USB.

Für Geräte mit 24V wird die 24v12 oder 24v23 Version empfohlen.

Beachten Sie bitte, dass Sie die Controller in der 18v7, 18v15 oder 18v25 nicht mit 24 V Batterien betreiben!

Key Features

  • Simple bidirectional control of one DC brush motor.
  • 5.5 V to 30 V (18v7, 18v15, and 18v25) or 40 V (24v12 and 24v23) operating supply range.
  • 7 A to 25 A maximum continuous current output without a heat sink, depending on controller model
  • Four communication or control options:
    1. USB interface for direct connection to a PC.
    2. Logic-level (TTL) serial interface for direct connection to microcontrollers or other embedded controllers.
    3. Hobby radio control (RC) pulse width interface for direct connection to an RC receiver or RC servo controller.
    4. 0–3.3 V analog voltage interface for direct connection to potentiometers and analog joysticks.
  • Simple configuration and calibration over USB with free configuration program (Windows 8, 7, Vista, Windows XP, and Linux compatible).

Note: A USB A to mini-B cable (not included) is required to connect this controller to a computer.

Additional Features

  • Comprehensive user’s guide with plenty of connection diagrams and sample code.
  • Adjustable maximum acceleration and deceleration to limit electrical and mechanical stress on the system.
  • Adjustable starting speed, maximum speed, and amount of braking when speed is zero.
  • Optional safety controls to avoid unexpectedly powering the motor.
  • Input calibration (learning) and adjustable scaling degree for analog and RC signals.
  • Under-voltage shutoff with hysteresis for use with batteries vulnerable to over-discharging (e.g. LiPo cells).
  • Adjustable over-temperature threshold and response.
  • Adjustable PWM frequency from 1 kHz to 22 kHz (maximum frequency is ultrasonic, eliminating switching-induced audible motor shaft vibration).
  • Error LED linked to a digital ERR output, and connecting the error outputs of multiple controllers together optionally causes all connected controllers to shut down when any one of them experiences an error.
  • Field-upgradeable firmware.
  • USB/Serial features:
    • Controllable from a computer with native USB, via serial commands sent to the device’s virtual serial (COM) port, or via TTL serial through the device’s RX/TX pins.
    • Example code in C#, Visual Basic .NET, and Visual C++ is available in the Pololu USB Software Development Kit
    • Optional CRC error detection to eliminate communication errors caused by noise or software faults.
    • Optional command timeout (shut off motors if communication ceases).
    • Supports automatic baud rate detection from 1200 bps to 500 kbps, or can be configured to run at a fixed baud rate.
    • Supports standard compact and Pololu protocols as well as the Scott Edwards Mini SSC protocol and an ASCII protocol for simple serial control from a terminal program.
    • Optional serial response delay for communicating with half-duplex controllers such as the Basic Stamp.
    • Controllers can be easily chained together and to other Pololu serial motor and servo controllers to control hundreds of motors using a single serial line.

    RC features:

      • 1/4 µs pulse measurement resolution.
      • Works with RC pulse frequencies from 10 to 333 Hz.
      • Configurable parameters for determining what constitutes an acceptable RC signal.
      • Two RC channels allow for single-stick (mixed) motor control, making it easy to use two simple motor controllers in tandem on an RC-controlled differential-drive robot (you might find our RC servo Y splitter cables useful for connecting two SMCs to a single RC receiver).
      • RC channels can be used in any mode as limit or kill switches (e.g. use an RC receiver to trigger a kill switch on your autonomous robot).
      • Battery elimination circuit (BEC) jumper can power the RC receiver with 5 V or 3.3 V.
  • Analog features:
    • 0.8 mV (12-bit) measurement resolution.
    • Works with 0 to 3.3 V inputs.
    • Optional potentiometer/joystick disconnect detection.
    • Two analog channels allow for single-stick (mixed) motor control, making it easy to use two simple motor controllers in tandem on a joystick-controlled differential-drive robot.
    • Analog channels can be used in any mode as limit or kill switches.

Most Simple Motor Controllers are available “fully assembled”, with the power capacitor and connectors pre-installed, or with these components included but not soldered in. For example, a fully assembled 18v15 ships as shown in the left picture above, and an 18v15 with included hardware ships as shown in the right picture above (the included hardware consists of a power capacitor, a 40×1 straight 0.1" male header strip, a 5mm-pitch 4-pin terminal block, and a blue shorting block).

The connector-free version allows flexibility in choice of connectors and placement of the power capacitor (e.g. on the other side of the board) to accommodate compact installations or to make room for a heat sink.

Note: The power capacitor has a significant effect on performance; the included capacitor is the minimum size recommended, and bigger ones can be added if there is space. A bigger capacitor might be required if the power supply is poor or far (more than about a foot) from the controller.

The included terminal blocks are only rated for 16 A, so we recommend soldering thick wires directly to the connector-free version of the board and using higher-current connectors for applications that will exceed the terminal blocks’ ratings.

Warning: Take proper safety precautions when using high-power electronics. Make sure you know what you are doing when using high voltages or currents! During normal operation, this product can get hot enough to burn you. Take care when handling this product or other components connected to it.
