Top 10 Reasons to Upgrade to ClearPath:

AC ClearPath Integrated Servo with red knockout cover
  • 1. Integrated — No drive to mount, no motor-to-drive cable to wire and route. Faster and easier installation.
  • 2. Full torque at zero/low speed — Hold position without a brake or clutch; eliminate speed-reducing gearboxes.
  • 3. Excellent velocity accuracy — Smooth and precise (within 0.001%), even at very low speed.
  • 4. Smaller and lighter — Takes up less machine space, and no panel/enclosure space; easier to handle and install.
  • 5. Easy to Use — Simple I/O control (see videos below); auto-tuner optimizes performance for every application.
  • 6. Reserve power when you need it — Most models have 300-400% peak torque capability to eliminate stalls from transient overloads, maintain accurate speed despite large load disturbances, and make fast, smooth starts and stops.
  • 7. Control position as well as velocity and torque; built-in, high-resolution encoder provides repeatability better than 0.006 degrees.
  • 8. IP65 sealed — Drive, controls and encoder are protected within the sealed, cast aluminum motor body; no expensive protective enclosures needed.
  • 9. Matched drive and motor — no worries about drive/motor compatibility issues or overall system performance.
  • 10. Low price, great value — Get a true, closed-loop PMAC servo for the price of an inverter-rated AC motor and VFD. Assembled in the USA, 3-month money-back guarantee, 3+ year warranty.

Standard Features

AC ClearPath with 13 callouts highlighting rugged industrial construction features
Impact-resistant, polycarbonate conduit box cover allows you to easily inspect your wiring and see the status LED.
Touch-proof, rising-clamp, screw terminal block provides easy, safe, and secure AC power connections.
Control torque, velocity, and position with simple, digital I/O (or step & direction, or C++ code, using the SD or SC models, respectively).
High-energy, neodymium permanent magents for high efficiency and maximum power density.
Wire insulation exceeds Class H ratings for extra robustness.
Rust and corrosion-resistant stainless steel shaft has a radiused turn-down at the bearing for increased strength.
Oversized 6206-size bearings have a 37% higher dynamic load rating than standard 6205 bearings, and are permanently lubricated and sealed to eliminate maintenance.
IP65 rated, electrophoretically-coated, cast aluminum body withstands rugged conditions.
Motor temperature is monitored by both software and hardware for maximum thermal protection.
Built-in soft-start reduces inrush current and prevents nuisance trips of circuit breakers.
Standard, built-in 64,000 count/rev encoder allows position control and exceptional (0.001%) velocity accuracy (fractional hp ClearPath motors are 12,800 count/rev).
Optically isolated I/O provide noise immunity, interface flexibility, and ruggedness.
USB port and free Windows® software lets you graphically see the performance of your motor and mechanics (torque, accuracy, and much more).

Optional Accessories

AC ClearPath with blower and foot mount assembled together as a complete unit
AC ClearPath with blower assembled together
  • The Blower Kit (AC powered fan and shroud) provides a significant increase in continuous torque and power for certain AC-input ClearPath motors.
  • The Blower Kit requires single-phase 190-230 VAC.
  • For information on mounting the Blower Kit to your ClearPath motor, take a look at the ClearPath user manual.
AC ClearPath with foot mount assembled together
  • The Foot Mount is an optional rigid base for AC-input ClearPath motors.
  • Customers can use the foot mount instead of the standard face mount for the NEMA 56 and NEMA 143 motors, or in place of the flange mount option with the IEC D100 motors.
  • For mounting instructions, refer to the ClearPath user manual.
ASU with marker to show scale
  • The Analog Send Unit (ASU) allows you to use analog signals (0-10V or 4-20mA) to control ClearPath.
  • The ASU converts these analog control signals to high-fidelity digital signals compatible with ClearPath.
  • For additional information on the Analog Send Unit, take a look at the ASU user manual.
Regenerated Energy Stunt standalone
  • The Regenerated Energy Shunt (RES-225) helps prevent nuisance over-voltage shutdowns by monitoring and dissipating your motor's regenerated energy.
  • The RES-225 is used in applications that experience significant regenerated energy. Generally these are vertical axes or those with large inertial loads that are decelerated quickly.
  • Each RES-225 can dissipate 250 Watts of continuous power, and up to 7kW of peak power.
  • For additional information on the RES-225, take a look at the ClearPath user manual.

Which mode is best for you?

Watch the demo videos below.


Spin at one or more different speeds(4 Operating Modes)

Ramp Up/Down to Selected Velocity:

By changing digital inputs (from your PLC, switches, etc.), ClearPath will smoothly ramp to one of four preset speeds in either direction.

watch video
Manual Velocity Control:

Fine control of speed from zero to max speed at the turn of a knob. Remembers your last set speed or resets to zero speed when motor is enabled.

watch video
Spin on Power Up:

Just turn on power and smoothly ramp to your preset speed. For when all you need is reliable, constant speed from a brushless motor, and a bare minimum of wiring. It doesn't get any easier than this.

watch video
Follow Digital Velocity Command:

Connect a digital waveform from your PLC or other device, and ClearPath will run at a speed proportional to the waveform. Or, connect the PWM output of an H-bridge drive of a DC brush motor setup to make a high-performance, drop-in replacement.

watch video

Apply a variable torque or tension(1 operating mode)

Follow Digital Torque Command:

Apply a variable torque (or force or tension) in proportion to a digital command (PWM or frequency).

watch video

Move back & forth between 2 positions(2 Operating Modes)

Move to Absolute Position (2 positions):

Trigger ClearPath to move to one of the two preset positions. Perfect for replacing air cylinders that move between two positions, but where more power and finesse is needed.

watch video
Move to Sensor Position:

Trigger ClearPath to move in either direction and it will smoothly ramp up to a chosen speed and stop when it detects a sensor (or switch).

watch video

Move between 4 or more positions(6 Operating Modes)

Move to Absolute Position (4 positions):

Trigger ClearPath to move to one of four preset positions. Perfect for replacing air cylinders where more power and finesse is needed.

watch video
Move to Absolute Position (16 positions):

Trigger ClearPath to move to one of 16 positions from a user-defined reference position.

watch video
Move Incremental Distance:

Trigger ClearPath to move a user-defined distance (one of four) from its current position. You can also send multiple, quick trigger pulses to tell ClearPath to travel a multiple of any of its user-defined distances in one smooth move.

watch video
Pulse Burst Positioning:

Use a timer/counter on your PLC (or a simple circuit) to send a burst of pulses to ClearPath, and it will move a distance proportional to the number of pulses sent, at your pre-selected speed and acceleration.

watch video
Multi-Sensor Positioning:

Define multiple positions using sensors or switches, and trigger ClearPath to start moving and continue until it sees the next sensor transition (or a user-specified number of sensor transitions).

watch video
Follow Digital Position Command:

ClearPath will move at a user-defined velocity to a position proportional to the frequency or PWM duty cycle of a digital waveform.
