General Specifications:
These DC explosion-proof
motors are designed and
approved for application in
hazardous environments
having certain explosive
gases or materials present.
Features include:
UL and CSA listed
NEMA 56C face with
removable 56-frame base
¾-14NPT Pipe nipple for lead
exit hole
Pilot-duty thermostats are
standard
Easy brush access for field
service
Double-shielded ball bearings
are pre-lubricated for the long
bearing life
Optional explosion-proof
conduit box available as a Kit
|
General Specifications:
These Metric motors are built
to IEC 34-1 electrical and
mechanical specifications.
The IEC 63 and smaller
frames are stocked with an
integral B5 flange or B14 face
less base. An optional B3
rigid base kit is available. A
unique modular approach for
IEC 71 frame and larger
allows the motor to field
modified to B3 rigid base
mounted construction using
conversion kits.
Electrical and Mechanical
Features:
Terminal Board provided for
connections
Fasteners are Metric
Tachometer mounting kits
available

These are General Purpose
drives designed for use with
Permanent Magnet or Shunt
wound DC motors. NEMA 1
enclosed drives are suitable for
most industrial applications.
The NEMA 4X controls are best
suited for washdown or outdoor
installations or for extremely
dusty applications. Chassis only
drives are available for building
into equipment, machinery or
existing enclosures. Most
controls have a dual voltage
switch allowing the control to
be used with either 115 volt or
230 volt, single-phase, input
power at either 50 or 60 Hz
service. It is important that the
proper voltage motor be
selected to use with the
available power supply.

Pulse Width Modulated
(PWM) controls are available
in NEMA 1 and chassis style
units for sub-fractional HP
frame motors from 1/40 HP
through ¼ HP. Due to their
improved form factor, these
PWM controls result in quieter
operation, lower operating
motor temperatures, longer
brush life and greater motor
overload capacity than for the
same motor on an SCR type
control
|
LEESON’s DC to DC
controllers are a chassis type
design, that accept a DC
input voltage and output a
DC power voltage to control
the motor’s speed. A
potentiometer is shipped
loose with the controls. On
board Trim Pots include
calibration, min/max speed,
forward and reverse settings
and an inhibit circuit for
convenient remote starting
and stopping.
