These DC motors uses 2 phase (quadrature) incremental encoders to detect the speed of the motor and the distance it has travelled.
These motors are designed to run at 6 to 24 volts DC and they draw less than 3 amps w/locked rotor. (This is normally referred to as the stall current and is usually the maximum current draw for the motor). Motors are rated at 12 VDC but can be kicked up to 24 VDC for short periods to get a higher power level if the amplifier used to run the motor can provide the needed power.
Controller and Amplifiers for these motors should be able to provide a continuous current of 3 amps and extremely short bursts of 6 amps. Popular, amplifiers and controllers based on the National Semiconductor LMD18200 series chips will do this.
Connector Kit CK-1
Provides two four pin encoder connector with pins and housings and a male/female power connector to simplify the connection of the motor to the controller and the motor power supply.
