Some of our products (Hudson, Meridian, Eclipse) are available only to OEMs with a minimum purchase requirement. We sell our fully-integrated ClearPath motors, ClearPath accessories, ClearCore and ClearLink controllers, and DC power supplies on our website. If you have questions about our products, please contact us for more information.
ClearPath-SD series servo systems are a perfect drop-in replacement for your stepper system. No more lost steps, whisper quiet motion, and increased machine throughput with 8-13x more power than similar size steppers.
Upgrade your current servo system with any of Teknic's ClearPath servo systems and get state-of-the-art performance in a compact and integrated package at an unbeatable price.
Being able to smoothly start and stop with 0.001% velocity accuracy, hold position without expensive mechanics, and the ability to access full torque at low RPM make ClearPath motors a must-have replacement for AC Induction motors.
Meridian is an integrated motion controller and digital servo drive that is capable of controlling servos, linear motors, and steppers. Benefits include:
Reduce machine vibration and increase throughput with g-Stop™ anti-resonance
Use the Accelerated Prototyping System™ to diagnose machine performance, reduce development time, and get your machine to market faster
Improve stepper motor smoothness and increase power output with Meridian's vector sinewave commutation
Meridian's "sFoundation" is a source code library that provides the majority of the motion functions you'll need to get your system up and running quickly
The Amazon™ Intelligent Power Center (IPC) is designed and built specifically for motion control applications.
High output capacitance and built-in regen control system prevents over-voltage shutdowns and the need for external regeneration control and load resistor
High peak power drastically reduces power supply droop during motor acceleration
ClearPath-SD combines a step & direction vector servo drive, brushless servo motor, and high-resolution encoder into one compact package.
Two ClearPath-SD models are available:▸ the SDSK model is a servo system for the price of a stepper motor/drive system, but 2-3 times the power;▸ the SDHP model is more than 4 times the power of the SK model, and although a modest price premium over the SK, compared to other similar power servos, the HP is about 50% lower cost and a compact, all-in-one system.

5 ClearPath-SDHP servos offer more power per dollar and more power per cubic inch than any non-integrated servos. State-of-the-art control algorithms harness this power for a great combination of power and finesse.
5 Most brushless servo systems have constant torque out to relatively high speed, which means lots of power.
3 ClearPath-SDSK servo systems have 2-3 times the power of similar sized steppers and cost less.
1 High inductance and high pole count causes torque to drop off rapidly with speed, leading to lower power output.
5 Very good, and ClearPath's proprietary anti-hunt feature eliminates most hunting. Encoder disk runout is minimized by using a precision machined shaft, a zero runout disk mount design, and a fixed rear bearing.
4 Very good, although some servos hunt (dither) if they use high resolution encoders. Also encoder disk runout affects accuracy.

3 Generally pretty good, but degraded by a variety of factors: friction, inertia, static forces, temperature, detent torque, etc.

1 Stepper motor systems can lose position or stall if not designed with a large safety margin.
5 Servos have no resonant zones like steppers, and ClearPath-SDHP will apply as much jerk-limiting (and jerk-derivative limiting) as required to reduce machine vibration and improve settling time.
3 Servos have no resonant zones like steppers. Smoothness of motion depends on the quality of the motion profile and tracking accuracy of the servo.
3 Servos have no resonant zones like steppers, and ClearPath-SDSK will apply a small amount of jerk-limiting (and jerk-derivative limiting) to help smooth out any imperfections in the motion profile output.
1 Steppers need to jump through speeds where they naturally resonate, which causes jerk on start and stop of motion.
5 Brushless servo systems are generally much quieter than stepper systems, and ClearPath uses special techniques to further reduce noise: vector AC commutation, skewed stator laminations, exterior rotor magnet design, oversized precision bearings, and others.

1 The large detent torque of steppers, and the way they operate, causes them to run noisy.
5 ClearPath automatically optimizes itself for whatever load is connected. Numerous servo control innovations allow ClearPath to easily handle load-to-motor inertia mismatches of more than 100:1.
3 Servos can be tuned to be a wide range of loads, but most servo manufacturers recommend staying within a 10:1 load-to-motor inertia ratio for acceptable performance.

1 Steppers must be mechanically "tuned" to the load friction and inertia in order to work properly. Stepper performance can not be optimized with software.
5 Brushless servos systems general have much less vibration than stepper systems, and ClearPath further reduces vibration due to the vector chatter common to many servo systems that use acceleration feedforward and/or aggressive torque loop gains.

1 For the same reasons that steppers are noisy, they also create a substantial amount of high frequency vibration.
5 Servos are energy efficient because (in theory) they only use current in proportion to the amount of torque needed. ClearPath uses resistance feedforward, back-EMF compensation, and inductance cross-coupling to come very close to theoretical maximum efficiency. This means that very little energy is consumed when the motor is running at constant speed or at rest.

1 Steppers typically run with at least 50% of full current at all times even when running at constant velocity or standing still. This wastes a large amount of energy and causes steppers to run hot even with low loads.
