NOTE: All chopper drive curves were created with a 5 volt motor and a 40 volt power supply.

Ramping can increase the performance of a motor either by increasing the top speed or getting a heavier load accelerated up to speed faster. Also, deceleration can be used to stop the motor without overshoot.

With L/R drives peak force and speeds are reduced, using a unipolar drive will yield a further 30% force reduction.

Lubrication Options +

Haydon® Super Slick Greases

Haydon offers a wide selection of greases designed to meet any application requirements. Please contact Haydon Kerk Motion Solutions for assistance in selecting the most effective lubrication option.

	Grease Type	Chemical Compatibility	Temp. Range	Comments	Cost
HSS-03	Polyolester	Good	-54°C to +150°C	Moderate Load	$
HSS-17	Synthetic Hydrocarbon	Good	-20°C to +125°C	Standard	$
HSS-06	Perfluoropolyether	Best	-65°C to +250°C	Tough Environments	$$
HSS-16	Perfluoropolyether	Better	-80°C to +204°C	Vacuum compatible	$$$
HSS-20	Perfluoropolyether	Best	-65°C to +250°C	High Repeatability	$$$

HSS-03

is a light viscosity, polyolester based grease thickened with PTFE. It is an economical alternative to premium PFPE (perfluoropolyether) types where low temperature performance is a primary requirement as it provides low starting torque.

HSS-17

is a medium viscosity synthetic hydrocarbon grease thickened with lithium soap. It is fortified with EP (extreme pressure) modifiers to increase load carrying capabilities and TFE to increase lubricity and reduce friction. Rated temperature capacity is -20°C to +125°C. HSS-17 has the highest load characteristics.

HSS-06

is a TFE thickened heavy viscosity perfluoropolyether grease. It is designed to operate in chemically harsh environments and provides excellent operating properties for light to medium loads. Rated temperature capacity is -65°C to +250°C. Standard on Hybrid Actuators.

HSS-16

is a perfluoropolyether grease developed for use in vacuum environments good to 4x10–13 torr at 20°C. Rated temperature capacity is -80°C to +204°C.

HSS-20

is an ultrafiltered version of HSS-06, meaning that the grease it put through a ‘cleaning’ process to remove any particles greater than 35 microns in size. It is designed for use when accuracy and repeatability are of utmost concern.

Black Ice® and Kerkote® TFE Coatings

Black Ice and Kerkote TFE coatings are available in some of our actuator designs depending on the nut polymer used. Please consult the applications engineering team to discuss lead screw nut / TFE coating compatibility.

Encoders +

All Haydon hybrid linear actuators are available with a specifically designed encoder for applications that require feedback. The compact optical incremental encoder design is available with two channel quadrature TTL squarewave outputs. An optional index is also available as a 3rd channel. The size 8 encoder provides resolutions for applications that require 250 and 300 counts per revolution. The size 11, 14 and 17 encoder provides resolutions for applications that require 200, 400 and 1,000 counts per revolution. The size 23 and 34 encoder is offered in resolutions of 200, 400, 1,000 and 2,000 counts per revolution. Encoders are available for all motor configurations — captive, non-captive and external linear.

Simplicity and low cost make the encoders ideal for both high and low volume motion control applications. The internal monolithic electronic module converts the real-time shaft angle, speed, and direction into TTL compatible outputs. The encoder module incorporates a lensed LED light source and monolithic photodetector array with signal shaping electronics to product the two channel bounceless TTL outputs.

Home Position Switch and Proximity Sensor +

Home Position Switch

Haydon offers a mechanical home position switch capable of monitoring the end position of Can-Stack and Hybrid captive linear actuators.The home position switch mounts on the rear sleeve of Haydon’s captive linear motors. This allows the user to identify start, stop or home positions of the actuator.Depending on your preference, contacts can be normally open or normally closed. The contact closure is repeatable to within one step position, identifying linear movements as low as 0.0005" (0.0013 cm) per step. Multiple contact switches are also available.The switch allows device manufacturers the ability to monitor movements more precisely for greater control and improved Q.C. When ordering motors with the home position switch, the part number should be preceded by an S. Contact Haydon Kerk Motion Solutions for additional ordering information. Activation force of 10 oz required, therefore may not be appropriate for smaller can-stack actuators.

Proximity Sensor

Haydon offers a miniature hall effect sensor capable of monitoring the end position of Can-Stack and Hybrid captive linear actuators.The sensor incorporates a hall effect device, which is activated by a rare earth magnet embedded in the end of the internal screw. The compact profile of the sensor allows for installation in limited space applications.The sensor has virtually unlimited cycle life. Special cabling and connectors can be provided. Haydon's end of stroke proximity sensor, and all Haydon Kerk Motion Solutions products are backed by a technical team which provides extensive customer support and applications assistance.
