20000 20mm

20000 Series Can Stack Stepper Motor Linear Actuator
PLEASE NOTE: This is a legacy product, not intended for new machine designs. Please consider an alternative HKP can-stack actuator.

The 20000 Series by Haydon Kerk Motion Solutions is a 20mm stepper motor linear actuator.  20000 series linear actuators are available in two designs - captive and non-captive versions.  Available in a variety of resolutions, ranging from 0.0254mm to 0.102mm per step.  The 20000 series can stack stepper motor linear actuators deliver force of up to 3.5 lbs (16N).  Applications include medical instrumentation, office equipment, appliances, optics, machinery automation and other automated devices which require precise remote controlled linear movements.

    25% Duty Cycle is obtained by a special winding or by running a standard motor at double the rated current.

    25% Duty Cycle is obtained by a special winding or by running a standard motor at double the rated current.



    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.  

  • High Temperature Option +


    Haydon offers a line of stepping motors specially designed for high temperature environments. The motors are constructed using the proven techniques employed for Haydon standard motors. Special materials which meet IEEE class F temperature ratings of 155° C are used in construction. Specialized components include high temperature bobbins, coils, lead wires, lubricant and adhesives. If your application requirements exceed 155°C contact our applications group for a customized solution.

  • Home Position Switch and Proximity Sensor +


     Home Position Switch
    Haydon offers a miniature electronic switch capable of monitoring the home 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.
