STM17 Integrated Size 17 Step Motor, Microstepping Drive, and Controller


Applied Motion Products is proud to introduce the STM17 drive+motor.  The STM17 integrates a size 17 step motor, microstepping drive and controller into a single device, offering savings on space, wiring and cost over conventional motor and drive solutions. The STM17 complements Applied Motion’s popular STM23 drive+motor family.

The "S" models accept step and direction, analog input, joystick control, and streaming host commands using the SCL language. "Q" models add standalone programmable operation using the Q programming language. This versatile language includes high-level features such as complex motion, multi-tasking, conditional programming, math functions, register access, and more. Both S and Q models offer RS-232 or RS-485 communication.  An optional 1000-line encoder, integrated into the motor housing, provides stall detection and/or stall prevention.  Applied Motion’s proprietary stall prevention algorithm monitors rotor lag and automatically reduces speed or acceleration to avoid motor stalls, allowing 100% torque utilization.

A CANopen version is also available, supporting the DS301 and DSP402 standards.

The STM17 provides up to 68 oz-in of torque and can be powered from 12 to 48VDC.  The STM23 is available in two sizes: a 2-stack version that provides 125 oz-in of torque and a 3-stack version with 210 oz-in of torque.  The STM23 can be powered from 12 to 70VDC.

All STM models are CE certified and ROHS compliant.  Matching DC power supplies are also available.  All STM models and compatible power supplies ship from stock.
