(1) With 24 volts drive.

(2) Values shown are for reference only and are correct to the best of our knowledge
at the time of publication, but are subject to change without notice.
Parameters to be used as part of a specification should be verified with the factory.

(3) Voltage shown is per phase at rated current at zero steps per second, with winding at 25°C.
Resistance tolerance and winding temperature will influence voltage.

(4) Tolerance is ±20%. Measured at 1 kHz with a General Radio #1650B impedance bridge having a
1 volt rms open circuit sinusoidal signal. Rotor position preconditioned by energizing same phase,
then deenergizing same phase during measurement without changing rotor position.
*These motors are obsolete and should not be used in a new application design.
They can be provided to support existing systems.
