NT series (Inverter Duty) NEMA standard
three phase asynchronous motors are Totally Enclosed Fan Cooled motors,
designed and manufactured to meet or exceed efficiency values of NEMA MG-1. The
motor has the characteristics of high efficiency, low temperature rise, low
noise and vibration, high starting torque, solid structure, durability, safety
and reliability.
Wonder NT Series are UL and CSA
certificated.
Wonder NEMA standard motors cover optional multiple
designs of A, B, C, D, making them suitable for different types of applications.
Special designs and manufacturing requirements can be customized, such as type TC
or TD, class H insulation, or different voltage and frequency.
NEMA Design A
Normal starting torque, high to medium
starting current, high breakdown torque, maximum 5% slip. Able to handle
heavy loads in a short time, well suited for variable speed operation,
exhibiting low slip and high efficiency.
NEMA Design B
Starting torque is similar to type A, but sometimes
lower. Providing a lower starting current.
It locks the rotor torque in industrial applications but still allows
the starting load. The slip is less than or equal to 5%. High efficiency and
high full load power factor. Well suited for variable torque, constant torque
and constant horsepower applications.
NEMA Design C
Provides high starting torque (higher than types A and B,
usually more than 200% of the rated torque). It is often used to drive heavy
starting loads. Low starting current. The slip is less than or equal to 5%.
Medium efficiency motors, well suited for equipment with high inertia and high
starting torques at start.
NEMA Design D
Provides the highest starting torque of all NEMA motor
types. Low starting current and full load speed. High slip (ranging from 5-8%
instead of 1-5%) creates a stronger torque.
The motors can run almost at full speed without overloading, well suited
for machinery with high peak loads.
