How to Handle Space Stepper Motors

MA 1313-A001 EN
The
maximum allowable power dissipation
of a stepper motor is always the same for all
connection modes. According to the connection mode, the motor windings receive different
currents. Therefore, the maximum allowable phase currents are determined by the con-
nection mode.
At
half-step or mini-step
operation of the control unit, the rated current is the r.m.s value.
The current tables in Phytron's power stage manuals show r.m.s. values.

6.2.1 Marking of the Leads
Space stepper motor wires are the same colour and are identified by coloured PTFE
tubes:

In case of motors with built-in type K thermal elements, the minus pole is magnetic.
