Why a CanStack motor Rear Coil Multipole Permanent Magnet Rotor & shaft Front Stator Cup, teeth & mounting plate Rear Stator Cup with stator teeth Pole Plate (inner stator teeth) Innovation & Performance Can Stack motion technology focuses on simplicity. This permanent magnet stepper motor uses the simplest of techniques and designs to create an effective solution for many applications, where reasonable accuracy and moderate torque are required. Portescap can trace its stepper heritage back to the invention of the can stack step motor. This is one reason why we offer one of the widest ranges...

CanStack Motor Operation What is a Permanent Magnet Stepper Motor CanStack motors are usually 2 phase in construction. They consist of two stator cups with claw tooth poles formed around a winding creating the front of the motor and the same applies to form the rear. The rotor has the same number of pole pairs as the stator. The poles on each stator cup are constructed to be a half a pole pitch apart and with two coils this means there can be 4 discrete positions per pole pitch. A 2 phase motor, for example, with 12 pole pairs in each stator / coil sector will therefore have 48 steps per revolution...

CanStack Motor Operation What is an AC synchronous motor? The AC Synchronous motors provided by Portescap are constructed in the same basic way as the permanent magnet motor except that each coil is supplied with AC voltage with a phase shifting capacitor across the coils. These motors run at fixed speed and are for continuous rather than intermittent duty (as is the case with step motors). For example, the speed of a 12 pole pair design run operated using a 50Hz supply will deliver 60 X 50/12 = 250rpm. At 60Hz the speed would therefore be 300 rpm. ADVANTAGES • Operated from AC main supply •...

How to select your CanStack motor Selection Criteria • The Torque – Speed Curves are essential for selecting the right motor and control drive method for a specific application. • Define your application load – speed required, load inertia, torque and accuracy needed. • If the application requires no acceleration, then use the pull out torque. • If the load is inertial (acceleration is required), it is advisable to use pull in torque. • Motor temperature rise is important – so ambient temperature and duty cycle are important selection factors • It is advisable to use 1.5 to 2 times the margin...
