Note: Changing any motor options will update your part number

ClearPath-ECSK combines a conformance-tested EtherCAT vector servo drive, brushless servo motor, and high-resolution encoder into one waterproof and dustproof package, saving space and eliminating complex and failure-prone cabling. Compared to ClearPath-ECHP models, the ECSK models have less peak torque, but are a lower price for any given amount of continuous (RMS) shaft torque and power.

1The RMS torque limit on certain motors is derated for operation in ambient temperatures above +40 degrees C. Contact Teknic for derating assistance.

2Wired according to Teknic's instructions, ClearPath surpasses STO (IEC 60204-1) Safe Stop 0 safety requirements. Contact Teknic for more information.

3A ClearPath servo system consists of a servo motor and a servo drive built into a single unit. The servo motor portion of the ClearPath system is UL-recognized. The UL status of the servo drive is pending and expected in late 2024.

AC Blower Kit

Blower Kit

Blower Kit
Part Number: BLOWER-1P230V
Connector: Screw Terminal Block
Length: Adds 2.12 in to motor length (see manual/3D models for specifics)
Input Power: Single-phase 190-230 VAC
Weight: 2.0 lbs

This blower kit (AC powered fan and shroud) provides a significant increase in continuous torque for certain AC-input (integral hp) ClearPath motors. Motor part numbers shown with a “_fan” after them show the increased specifications using this blower. Note that this kit is not IP rated for dust or liquid protection, and needs AC wiring separate from the motor. For wiring and installation instructions, refer to the user manual: AC Input, Integral Horsepower ClearPath Motors
