Applications
Typical applications for these motors include:
Variable torque loads Applications include: Fans, blowers and centrifugal pumps.
Torque varies as the square of the speed, and horsepower as the cube of the speed.
Operation below base speed significantly lightens the load on the motor. While most variable torque
applications do not require the motor to operate below half speed, the motor is fully capable of operation
to zero speed. Operation above base speed significantly adds to the load on the motor; therefore, you must
carefully review applications requiring variable torque above base speed. Refer to the product technical
specifications for use of general purpose three phase motors on variable frequency drives.
Constant torque loads: Conveyors, elevators, hoists, extruders, positive displacement pumps, mixers and converting equipment.
Torque remains constant throughout the range of operation, and extra care should be taken in the proper
application of motors, especially at very low speeds. Most constant torque (C.T.) applications don’t require operation
below 10:1 (i.e. 6 Hz operation on a 60 Hz motor), but an increasing number of applications historically reserved for
servo and/or stepper systems are being served with motors capable of operation beyond 20:1…even up to 2000:1 (zero speed,
constant torque).
Applications requiring greater than 20:1 C.T. are ideal for MicroMAX®, Black Max® or Blue Max® motors.
These motors provide full rated torque within their listed speed range, without exceeding a Class F temperature rating
while under inverter power (many operate at Class B). Ratings have been developed, based on extensive testing on
IGBT inverters, set at a minimum 3 KHz (or equivalent) carrier frequency.
These vector-duty and inverter-duty motors are designed for operation at 150% of rated load for one minute, up to
the base speed of the motor (overload capability declines to 100% as the motor reaches maximum constant HP speed).
These motors accommodate constant horsepower operation to 1-1/2 to 2 times base speed, subject to the motor’s maximum
safe mechanical speed limit. Please refer to product technical and performance specifications for each motor’s capability.
Motors rated for zero RPM continuous duty (1000:1 or 2000:1) must be powered by vector drives to produce rated torque
without overheating. Optimum zero speed and low-speed full torque performance may require a closed loop vector drive
(with encoder feedback).
Constant horsepower loads Applications include: Coil winders, band saws, grinders, and turret lathes.
Operation requires the motor to deliver the same
horsepower rating, regardless of shaft speed. Torque increases at low speed and decreases at higher speed. Most general
purpose motors can deliver constant horsepower up to 1 1/2 times base speed. However, many constant horsepower applications
require operation to twice base speed, and some, such as coil winders, up to 4 times base speed. MicroMAX®, Black Max® and
Blue Max® motors are designed for 1 1/2 to 2 times base speed.
Other Application Considerations:
Horsepower or torque requirements at various speeds
Desired speed range of the load and motor
Acceleration and deceleration rate requirements of the process being controlled
Starting requirements including the frequency of starting and a description of the load (reflected
inertia at the motor, load torque during starting)
Whether the application is a continuous process or duty cycle of starts, stops and speed changes
A general description of the type of application including the environment in which the VFD system
components must operate (determines motor enclosure and/or explosion proof classification)
Description of the available electrical power supply and wiring
Special performance requirements, if any
Whether the drive will be configured with a by-pass circuit. In case of its deployment, the motor will operate
like its fixed speed counterpart and may require a
NEMA B design which limits in-rush current, or selection of a larger motor starter or other protective circuitry.
NOTE: Please be aware of shipping restrictions on motors before placing your motor order.
Most of the MicroMAX series motors are
currently available as in-stock items and will ship the same day from
AutomationDirect, but the larger non-stock motors that must ship via
truck (Black Max, Blue Max and Blue Chip-XRI Series motors) will be
drop-shipped from Marathon Electric (usually the same business day or
within 24 hours).
Motors with Encoders (Yxxx-A77x part numbers) are custom assembled and will drop-ship from Marathon Electric within 48-72 hours.
SHIPPING RESTRICTIONS ON LARGE MOTORS:
Due to current weight restrictions, large motors that must be shipped via truck cannot be shipped to Alaska, Hawaii, Puerto
Rico or the Virgin Islands.
"NEXT DAY" truck delivery options on motors are only available for a very limited number of in-stock items and
are subject to regional limitations. Orders must be placed no later than 12:00pm (noon) Eastern time and...
AN EXPEDITE FEE WILL BE CHARGED.
Saturday delivery is NOT available for motors that must ship via truck (ground service).
In-stock motors will typically ship the same day via the AutomationDirect preferred shipping provider.
