These high efficiency motors meet North American performance standards and EPACT energy efficiency mandates. They have a service factor of 1.15.
Typically used for replacement on machine tools, textile machinery and other equipment with metric dimensions, but requiring the heavy-duty torque and performance of motors designed for use in North America.
Two frame constructions are offered: aluminium frame and cast iron frame.
Both types are built to meet International standards and feature IP55 weatherproof enclosures, 60/50 Hz interchangeability (60Hz 230/460 V & 50Hz 200/400V), dual stamped nameplates, CE mark.
Kits are available for field conversion from B3 to B3/B5 or B3/B14. |

PICTURE KEY:
A. Drain hole knockouts located in multiple locations.
B. D flange (B5) and C face (B14) models available. Field conversion kits also offered.
C. "Captive shaft" keyway.
D. Drilled and tapped shaft.
E. Oil seals on both the drive end and non drive end.
F. High efficiency design utilizes low-less steel laminations for optimum power and performance.
G. Removable feet.
H. Class F insulation system with Class B temperature rise or lower.
I. Aluminium "full fact" nameplate with information on motor efficiency and power factor. Stamped with 60 Hz and 50 Hz data.
L. Multi-mount repositionable feet allow for three conduit box positions (F2, F1, F0).
M. External grounding provision.
N. Special design steel fan cover and low-noise fan maximize airflow efficiency.
O. Roomy conduit box is fully gasketed and has four-position conduit box entry (90 degree increments). NPT threaded entrance.
P. Includes terminal board.
Q. IP55 weatherproof enclosure allows for use in a wide range of applications. |
1. Terminal board included.
2. IP55 weatherproof enclosure allows for use in a wide range of applications.
3. D flange (B5) and C face (B14) models available. Field conversion kits also offered.
4. Drilled and tapped shaft.
5. Oil seals on both the drive end and non drive end.
6. Cast iron mounting feet are precision machined for accurate alignemnt.
7. Class F insulation system with Class B temperature rise or lower.
8. Stainless steel "full fact" nameplate with information on motor efficiency and power factor. Stamped with 60 Hz and 50 Hz data.
9. Steel fan cover.
