Electric Motor Data, fixed speed
General:
Electric motors are wired to operate in a Clockwise rotation, when
viewed from top of mixer looking downward into the mixing
container.
The mixers are supplied with the following power connections:
• 115 volt single-phase totally enclosed (TEFC) motors are wired
at our factory for correct rotation. All single-phase TEFC models
are equipped with cord, plug and switch assembly that are ready
to operate.
• 230/460 volt three-phase and all explosion-proof motors must
be field wired for proper rotation. Three-phase and explosion-
proof models are equipped with motor leads only. Refer to the
connection diagrams on the motor.
• DC Variable-speed models, the speed controller is mounted
and pre-wired directly to mixer.
- 115 volt single-phase totally enclosed (TEFC) motors are wired
at our factory for correct rotation. These models are equipped
with cord, plug and switch assembly that are ready to operate.
- 230 volt single-phase totally enclosed (TEFC) motors are wired
at our factory but have no plug.
Described below are the most commonly used electric motor
enclosure types on your INDCO mixer:
TEFC
- Totally Enclosed Fan Cooled - no ventilation openings in
housing (but not airtight, waterproof, or explosion-proof). Includes
an external fan, in a protective shroud, to blow cooling air over
the motor. Used in locations which are dirty or dusty.
TENV
- Totally Enclosed Non-Ventilated - no ventilation openings
in housing (but not airtight, waterproof, or explosion-proof). Relies
on convection for cooling. Used in locations which are dirty or
dusty.
EP
- Explosion-Proof - a totally enclosed design to withstand an
internal explosion of specified gases or vapors and not allow the
internal flame or explosion to escape. Explosion-Proof motors
are individually rated for specific gases, vapors & conditions. Most
INDCO EP motors are Class I, Group D & Class II, Group F & G
rated.
Warning:
These instructions must be followed to ensure safe and proper
installation, operation and maintenance of the motor. They should
be brought to the attention of all persons who install, operate or
maintain this equipment. Failure to follow instructions and safe
electrical procedures could result in serious injury or fatality.
Disconnect all power and discharge all capacitors before servicing.
Install and ground per local and national codes. Consult qualified
personnel with questions or if repairs are required.
Electrical Connections:
If your new mixer has not been supplied with a power cord
assembly by INDCO, see information below and consult your
local electrician or electrical code for proper size requirements.
1.
All wiring, fusing and grounding must comply with National
Electrical Codes and local codes.
2.
To determine proper rotation and voltage connections, refer
to the information and diagram on the nameplate, separate
connection plate or decal. If the plate or decal has been
removed, contact INDCO or the motor manufacturer for
assistance.
3.
Use the proper size of line current protection and controls
as required by the National Electrical Code and local
codes. Recommended use is 125% of full load amps as
shown on the nameplate for motors with 104°F (40°C)
ambient and a service factor over 1.0. Recommended use
is 115% of full load amps as shown on the nameplate for
all other motors. Do not use protection with larger
capacities than recommended. Three phase motors must
have all three phases protected.
Location:
In selecting a location for the motor, consideration should be given
to environment and ventilation. A motor with the proper enclosure
for the expected operating condition should be selected.
The ambient temperature of the air surrounding the motor should
not exceed 104°F (40°C) unless the motor has been especially
designed for high ambient temperature applications. The free
flow of air around the motor should not be obstructed.
The motor should never be placed in a room with hazardous
process, or where flammable gases or combustible material may
be present, unless it is specifically designed for this type of service.
1.
Drip proof (open) motors are intended for use indoors where
atmosphere is relatively clean, dry and noncorrosive.
2.
Totally enclosed motors may be installed where dirt, moisture
and corrosion are present.
3.
Totally enclosed – severe duty motors are recommended for
extreme environmental conditions.
4.
Explosion proof motors are built for use in hazardous
locations as indicated by Underwriters’ label on motor.
Consult UL, NEC and local codes for guidance.
Changing Rotation:
1.
Keep hands and clothing away from rotating parts.
2.
Before the motor is coupled to the load, determine proper
rotation.
3.
Check rotation by jogging or bumping. Apply power to the
motor leads for a short period of time, enough to just get
motor shaft to rotate a slight amount to observe shaft-rotating
direction.
4.
Three phase – interchange any two (2) of the three- (3) line
leads. Single phase – reconnect per the connection diagram
on the motor.
Inverter Control Data
If your HS Series mixer has the electronic inverter-duty
variable speed control, see enclosed Baldor owners manual.
