Pololu Simple High-Power Motor Controller 18v15
The Pololu Simple High-Power Motor Controller makes basic control of brushed
DC motors easy, with our free Simple Motor Control Center software enabling quick configuration over USB.
The controller supports four interface modes: USB, TTL serial, analog voltage, and hobby radio control (RC).
This version operates from 5.5 to 30V and is efficient enough to deliver a continuous 15A without a heat sink.
It ships with the power capacitor and connectors included but not soldered in, allowing for custom installations.
The Pololu Simple Motor Controllers are versatile, general-purpose motor controllers for brushed, DC motors.
A wide operating range of up to 5.5–40V and the ability to deliver up to several hundred Watts in a small form factor make these controllers suitable for many motor control applications.
With a variety of supported interfaces—USB for direct connection to a computer,
TTL serial for use with embedded systems, RC hobby servo pulses for use as an
RC-controlled electronic speed control (ESC), and analog voltages for use
with a potentiometer or analog joystick—and a wide array of configurable settings,
these motor controllers make it easy to add basic control of brushed DC motors to a variety of projects.
Although this motor controller has many more features than competing products, a free configuration utility
(for Windows 7, Vista, Windows XP, and Linux) simplifies initial
setup of the device and allows for in-system testing and monitoring of the controller via USB.
Key Features
- Simple bidirectional control of one DC brush motor.
- 5.5V to 30V (18v7, 18v15, and 18v25) or 40V (24v12 and 24v23) operating supply range.
- 7A to 25A maximum continuous current output without a heat sink, depending on controller model
-
Four communication or control options:
- USB interface for direct connection to a PC.
- Logic-level (TTL) serial interface for direct connection to microcontrollers or other embedded controllers.
- Hobby radio control (RC) pulse width interface for direct connection to an RC receiver or RC servo controller.
- 0–3.3V analog voltage interface for direct connection to potentiometers and analog joysticks.
-
Simple configuration and calibration over USB with free configuration program (Windows 7, Vista, Windows XP, and Linux compatible).
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 1kHz to 22kHz (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 1200bps to 500kbps, 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.
-
Controllable from a computer with native USB, via serial commands sent to the
-
RC features:
- 1/4µs pulse measurement resolution.
- Works with RC pulse frequencies from 10 to 333Hz.
- 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 5V or 3.3V.
-
Analog features:
- 0.8mV (12-bit) measurement resolution.
- Works with 0 to 3.3V 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.
