Motor Technology - POWERMAX II® series
request details NEMA23 stepper motors up to 1.8Nm
view printer friendly page  

 

 

 

The motors in size NEMA 23 have an octagonal housing, which shows the structure of the stator lamination.


The rear end bell can be equipped with an 8-pole plug for motor connection.

 

In standard version all motors have an 8-pole flying lead connection.

 

The standard types are available in several lengths and have torques of up to 1,8 Nm.

 

 

Motor design

 

 

 

P series Standard Hybrid Step Motor

 

M series Sigmax® Hybrid Step Motor

 

Typical path of flux transfer in an energized conventional hybrid step motor. Some flux leakage occurs in normal operation.

 

Patented Sigmax® technology redirects magnetic flux to inhibit leakage and optimize torque production.
