Integrated Motor Driver with Encoder NEMA 17, 1.8º Bipolar Step Motor Operates from +12 to 24 VDC Phase current ranges from 0.35 to 2.0 Amps Peak Step Resolutions from Full, Half, 1/4, and 1/8 microsteps Optically isolated Step, Direction, and Disable/Enable Inputs Selectable Current Reduction of 33% Low Power Dissipation Efficient Current Control Thermal Shutdown, Under-voltage Protection Up to 85 oz-in (60 N-m) of Holding Torque
IMDE17 has a NEMA Size 17 Step Motor, and comes in three different sizes:
IMDE17 comes with a built-in Encoder*
* The IMDE17 has the optical encoder option. The encoder can be used to monitor speed, direction, and distance of travel. A controller measures the process' speed by simply timing how fast the encoder supplies pulses. It determines direction by monitoring which channel (A or B) rises first. It determines distance traveled by counting the number of pulses sent since movement began.
