Integrated microstepping motor
Integrated microstepping motor and drive now available as entry-level step and direction control only.
USA motion control specialist Applied Motion Products Inc. (AMP), 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 3 digital inputs that accept pulse/direction and enable/disable motor power signals at 5-24 VDC. 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 12-48 VDC for the 17-frame motor, and 12-70 VDC for the 23-frame version. The maximum holding torque spans 50 to 150 Ncm through the range.
AMP's full range of STM integrated motors with integrated drive and controls combine all motor and electronics components into a single device offering a space-saving design that reduces wiring and saves on cost over separate motor and drive solutions. Control options include the STM-Q controller version that uses AMP's high-level Q programming language to write sequences of complex multi-tasked motion and machine control with full electronic gearbox, maths and registration functions. Other control options include CANopen as well as Ethernet/IP versions.
Mclennan fully supports the complete AMP range which also extends to servo motors with drives and motion controls that may be freely mixed with its stepper motor products for cost competitive motion systems for a wide range of machine building applications. Mclennan supplies a complete range of brushed and brushless servo motors, stepper motors and complementary drive technologies together with motion controls from a small number of global distribution partners. From its Hampshire based production and design facility the motion specialist supplies a complete range from component level products to complete integrated mechatronics assemblies with customised mechanics, special electrical interfacing, precision gearheads and other powertrain components.
