PennBarry Breezeway - Motor Selection

After choosing a fan model, it is important to review the motor
availability charts to verify that the desired voltage, phase and
motor enclosure is available. Some factors affecting motor
selection are discussed below.
Electric Power Considerations
First, determine the nature of the electric power feeding
the motor. Is it single phase or three phase power? Next,
determine the required line voltage. Is it 115V, 230V, 460V?
Then determine the frequency. Is it 60 Hz or 50 Hz?
Environmental Considerations
Most clean air fan applications utilize Open Drip-Proof
(ODP) motors. Hazardous environments require Explosion
Proof motors. Explosion Proof motors are rated for NEMA
Class 1, Group D, Div. 1 and Class II, Groups F and G,
Div. 1 applications. Dirty environments require TE motors.
Ambient temperatures above (50 deg C) require special
motor construction. When in doubt, consult your PennBarry
representative or the factory for application assistance.
Caution: Hazardous environments also require special
fan construction suitable for the conditions.
Fixed Speed Motor Control
Two-speed motors, used in conjunction with external switches
or sensors (gas concentration, odor, temperature, etc.), are
used to adjust the airfl ow through the ventilator by changing
from one fi xed speed to another. Typical two-speed motor
designation is 2-speed, 2-winding (1800/1200 Nominal RPM).
2-speed, 1-winding motors (1800/900 Nominal RPM) are
available for 3-phase power only. Dual voltage motors are not
available in a 2-speed confi guration.
Variable Speed Motor Control
PennBarry Lek-Trol™ solid state controllers are an economical
way to reduce the high speed of selected P Series motors
by as much as 50%. Check the Lek-Trol™ availability table
on the following page to verify suitability for the fan model
selected.
Motors suitable for use with fi eld supplied Frequency Inverters
can be supplied for BLL, BHM, BHH, BC and BCH models.
Contact your PennBarry representative.
High-Effi ciency Motors
Motors that comply with the requirements of the energy Policy
Act of 1992 are provided when the required voltage, speed
and enclosure are applicable.
