The STM Drive+Motor solution from Applied Motion Products (Watsonville, CA) is a stepper drive and motor unit fused into a single device that saves space, wiring and cost, when compared with conventional motor/drive solutions.
Advanced current control, anti-resonance technology, torque ripple smoothing and microstep emulation allow the STM to deliver optimized stepper performance ideal for medical, packaging, semiconductor and other automation applications. The drive and motor are protected against over and under voltage, over-temp, motor shorts and motor open phase. They are RoHS compliant and CE certified.
The STM is available in lengths of 92.4 mm with an output torque of up to 125 oz-in, or 114.4 mm with an output torque of up to 245 oz-in. They provide three digital inputs, one digital output and one analog output. Users can choose from an RS232 or RS485 communication interface and an optional 1000 line encoder integrated to the motor body.
Two versions with different control options are available; the S version with step and direction input, and the programmable Q version.
