Bi-Directional Ball Type |
| 115 VAC motor is
an enclosed, permanent split capacitor induction type. Load /
no-load speeds are approximately equal. The motor is equipped with
a thermal overload device that opens and resets automatically.
Standard motor requires 28-33 mfd
capacitor supplied by either the customer, or Duff-Norton at extra cost,
for loads up to 250 pounds. High speed motors require a 64-72 mfd
capacitor, also available from Duff-Norton. A capacitor box is
available on AC models only. |

|
220 VAC motor is
totally enclosed, permanent split capacitor induction type.
Load/no-load speeds are approximately equal. Equipped with thermal
overload device that opens and resets automatically. Standard
motor requires 10 mfd
440VAC, 60/50Hz metalized polypropylene capacitor supplied by
Duff-Norton. |
|
Additional
Notes |
- Some actuator surface temperatures may reach
230°F at or near maximum allowable duty cycle.
- The thermal overload resets in 10
minutes.
- All ratings are normal and based on
the actuator being broken in for approximately 2500 inches of travel.
