Speed/Torque Curves
The following speed/torque curves represent the available shaft torque at different
operating speeds. Operation at 120VAC and 240VAC is shown for each motor size.
Actual motor torque may vary ±10% due to motor manufacturing variances. For
operation from a 1-phase 120VAC, the output torque stays relatively constant and the
top-end speed falls off at the ratio of the input voltage (i.e., A Z610 operating at 240VAC
has a rated speed of 7000 rpm; operating at 120VAC, it will have a rated speed of 3500
rpm).

Helpful Hint:

Continuous Duty
means steady state
operation for drive
ambient temperatures
of 0°C to 50°C.
Intermittent Duty
means operation for
3.3 seconds or less.
