Motion Control 
and Encoders

Motion Control & Encoders
Motion Control Sure Products

Motion control typically refers to systems with accurate position/velocity/torque capabilities operating in either open or closed loop mode. Open loop stepping drives send motion commands to stepper motors, but receive no information about the result. Closed loop servo systems have feedback devices at the motor shaft to verify or adjust the resulting motion.

 

LS Electric® L7C Servo Systems -
Servo Motors and Servo Drives

LS Electric L7CA servo systems combine a high-performance servo motor with a servo amplifier (drive) to achieve accurate position, velocity, or torque control. Automatic tuning, built-in indexer and other standard features make this series an extremely cost-effective offering. Select system size based on power/torque requirements. Add power and feedback cables plus an I/O breakout module for a complete system.

Use our L7C Servo Selector Tool to size your system, and to specify all the required and optional accessories for your application.

SureServo®2 AC Servo Systems - Servo Motors and Servo Drives

 

SureServo2 Systems: 8 standard servo drives, 14 standard servo motors ... 100W to 15kW ... New!


The AutomationDirect SureServo2 family of brushless servo systems is the newest edition of our flagship SureServo family. SureServo2 offers even more power and features (and at lower cost) than our previous offering. There are 14 standard permanent magnet servo motors that can be operated in combination with one of eight standard servo drives:
 

  • Precise control of position, velocity and torque at incredible prices!

  • 15 standard systems from 100W to 15kW

  • 120VAC or 230VAC single-phase input power up to 2kW (and all models accept 230VAC 3-phase input)

  • Use with AutomationDirect CLICK, Do-more BRX, or Productivity series PLCs; or any other host controller or HMI

  • Professionally manufactured cables for motor power, encoder feedback, and brake (optional), in standard or continuous flexing versions (3m, 5m, 10m, or 20m lengths)

  • On-board motion controller with registration, electronic camming, and event-based logic control

  • Option modules for EtherNet/IP and Modbus TCP provide factory networking capability

  • External encoder support provides full closed-loop control (i.e. to compensate for slippage between motor and load)

  • 24-bit encoder has over 16 million PPR resolution (that's >46k pulses for ONE degree of motion). And the drive will scale to any input pulse resolution, while still maintaining this high degree of internal accuracy for all moves

  • Absolute encoder (via battery backup) never loses position, even when drive power is disconnected

  • Safe Torque Off (STO) for machine safety compliance without using bulky, expensive contactors

  • Configuration software (FREE download here, or order on USB device) allows for parameter upload/download, multiple auto-tuning modes, and includes a built-in oscilloscope for diagnostic and troubleshooting

SureGear® High-Precision Inline Strain Wave Gearboxes ... New!

 

Strain wave gearboxes offer many advantages over planetary and helical gearboxes, such as much higher gear ratios, higher efficiency, lower heat and noise generation, and zero backlash. Available in ratios up to 200:1 and a selection of output shaft diameters, these SureGear strain wave gearboxes are designed to work with our SureServo and SureStep motors.

 

SureGear strain wave gearboxes offer many advantages over planetary and helical gearboxes. Strain wave (also known as harmonic) gearboxes allow for a higher gear ratio compared to the same sized planetary gearbox. They also generate less heat and noise and are more efficient. These gearboxes are designed to work with SureServo2 motors (up to 10kW medium-inertia) and SureStep stepper motors (or other small NEMA frame motors).

  • Stressproof output shaft, high tensile strength, resistant to fatigue and excellent wearability

  • Output flange has a precision pilot

  • Double-row angular contact bearing provides a precision output with high stiffness,
    and high radial and axial load capacities

  • Flexspline progressively engages with the circular spline with a zero backlash tooth mesh

  • Precision shaped circular spline remains stationary and engages with the Flexspline

  • Wave generator elliptical ball bearing turns with input motor and causes the rotating elliptical wave form on the Flexspline

  • Precision sealed bearing axially fixes the input shaft and wave generator positions

  • Quick-connect motor coupling provides reliable and simple connection

  • Factory-machined input flange match SureServo2 and SureStep motors

SureStep® - Stepper Systems

 

SureStep® is an open-loop stepping system that provides simple and accurate control of position and speed, and offers a low cost motion control solution with up to 1200 oz-in of torque

Programmable logic controllers (PLCs) or other indexers and motion controllers act as a stepper motor controller to send step pulses and direction signals that are received by the Standard stepper drive to allow very precise motion control.

The Advanced stepper drives also accept pulse inputs, but they also can be commanded by an analog speed signal or by serial communication. The SureStep stepping system series includes:

  • Two DIP-switch configurable microstepper drives

  • Two software configurable advanced microstepper drives

  • Two braking accessories

  • Four step motor power supplies

  • Twenty stepper motors (NEMA 17, 23, 34 frame sizes) - now available in single and dual-shaft models
