Integrated microstepping motor and drive option

Integrated microstepping motor and drive option USA motion control specialist Applied Motion Products, represented exclusively by Mclennan Servo Supplies, has launched a new low-cost version of its STM series NEMA 17 and 23 frame stepper motors with integrally mounted microstepping drive and control. The new STM-R strips down the choice of control options available through the range to offer only step and direction or cw/ccw pulse control modes. Offering best value for OEM applications, the units are designed for use with an external controller that would typically provide one of these types of step/pulse signals.

STM-R integrated steppers include three digital inputs that accept pulse/direction and enable/disable motor power signals at 5-24V DC. A single digital output is included for drive and motor fault. The drive uses the same sophisticated current control, anti-resonance, torque ripple smoothing and microstep emulation that is found throughout the STM series. Users requiring stall detection or position verification can choose an optional 4000 count/rev encoder option to use in conjunction with their own controller to monitor encoder position whilst commanding motor position.

The STM-R 17-frame size motor boasts a 2A per phase current capability whilst the 23-frame, available in two stack lengths, has a 5A per phase peak. The STM-R is designed for operation between 12-48V DC for the 17-frame motor, and 12-70V DC for the 23-frame version. The maximum holding torque spans 50 to 150Ncm through the range.
