Can-Stack Rotary Motors

Z26000 26mm

Z26000 Series Haydon Rotary Can Stack Stepper Motor

Haydon's can-stack rotary stepper motors are built to provide exceptionally high torque to size ratios. The Haydon Z26000 can-stack rotary stepper motor is a 26mm high torque rotary motor with a holding torque of up to 1.8 oz-in(1.27Ncm). Typical applications include medical equipment, bar code scanning devices, printing equipment, laboratory instrumentation and other high torque, small space mechanisms.

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.

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