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.

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. |
