Motor Mind B Är en drivmodul för Likspänningsmotorer. Motor Mind styrs via seriellt interface och den kan styra hastighet och rikting på en elektrisk motor såväl som rapportera tillbaka aktueelt varvtal. Den är mycket enkel att ansluat och använda med en BASIC Stamp. eller serieporten på en dator.

Motor Mind B (#27961)

Data:
  • Controls a DC motor's direction and speed (up to 30 Vdc);
  • Easy to use 1 or 2 wire, 2400 baud serial interface;
  • Optional tachometer input reads up to 65,528Hz;
  • Supports peak currents as large as 3.5A and continuous currents of 2A;
  • External emergency override input (brake) shuts down motor;
  • Optional confirmation byte for electrically noisy environments;
  • 9-pin SIP package;
  • Small size (1.6" W x 1.2" H x 0.4" D).

Pin Configuration and Mechanical Specs:
The five-pin header on the StampMem board provides the required three-wire connections in a symmetric form (with serial I/O in the center) to allow for a reversible connector.

 Motor Mind B Commands:
Command Value Description
STOP 00h Stops the motor
REV 01h Changes the direction of the motor
TACH 02h Returns the frequency of the tach_in pin
SETDC 03h Sets the speed of the motor by adjusting the voltage in units of Volts/254
SPDCON 04h Sets the speed of the motor as a desired frequency. This will activate automatic speed control where the Motor Mind monitors the tach_in pin to maintain the desired speed.

The Motor Mind package includes:
  • Motor Mind with heat sink;
  • Printed documentation with sample BASIC Stamp I and BASIC Stamp II code.

The Motor Mind's small size and connection scheme allows the device to be inserted directly into circuit boards for production runs, or into breadboards for easy prototyping.
The Motor Mind has additional uses other than just motor control. One example is to use an external voltage to frequency converter and the tachometer function to provide a regulated charge voltage for a battery.
