Product Description:
The E31NCFT-LNN-NS-01 is another one of Kollmorgen’s robust step motors under the E/H stepper motor series. Featuring a size-34 NEMA frame, this stepper motor has a diameter of 3.38 inches. It features a single stack and supports NEMA through-hole mounting. It has a total of 8 lead connections and a type T-winding, allowing it to achieve its maximum torque at low speed. Unlike other stepper motors by Kollmorgen under the SIGMAX series, the E31NCFT-LNN-NS-01 has a laminated rotor without a built-in feedback system. Without a resolver or encoder, this stepper motor relies mainly on the amplifier or drive to provide information about the rotor’s angular position or speed during operation.
As part of the E31NCxx series, the E31NCFT-LNN-NS-01 has a maximum housing length of 91.95 millimeters. Like other E32XX motors, the E31NCFT-LNN-NS-01 has a mounted thermal resistance of 2.7 degrees Celsius per watt. The thermal resistance of motors represents how easy it is to dissipate generated heat to the environment. The higher the value of thermal resistance, the harder it is to facilitate heat transfer, leading to higher operating temperatures. The E31NCFT-LNN-NS-01 also has a rotor moment of inertia of 0.0170 oz-in-s^2. With this low rotor inertia, this stepper motor can easily achieve its rated speed quickly. For motors, the rotor moment of inertia represents how hard it is to accelerate the shaft from a stationary state.
With its frame type and construction, the E31NCFT-LNN-NS-01 has a listed weight of 5.3 pounds, or about 2.40 kilograms. Considering its shaft characteristics, the E31NCFT-LNN-NS-01 can tolerate a maximum radial force of 35 pounds or 156 N and a maximum axial force of 180 pounds or 801 N.
Frequently Asked Questions about E31NCFT-LNN-NS-01:
Q: What is the difference between the axial and radial force in the E31NCFT-LNN-NS-01’s specifications?
A: For the E31NCFT-LNN-NS-01, or any type of motors, the axial force represents the amount of loading that the motor can withstand against forces directed parallel to the shaft’s main axis or center. On the other hand, radial forces represent the amount of loading that a motor can withstand against forces directed perpendicular to the shaft’s tangential surface.
Q: Why is the E31NCFT-LNN-NS-01’s axial force rating greater than the radial force rating?
A: E31 motors have a high load-bearing design, allowing them to withstand high axial forces. For this reason, they perform well for drilling applications.
Q: What is the difference between a stepper motor such as the E31NCFT-LNN-NS-01 and traditional servo motors?
A: Compared to traditional servomotors, stepper motors such as the E31NCFT-LNN-NS-01 move in discrete precise angular steps.
Q: What certifications or approvals are applicable to the E31NCFT-LNN-NS-01?
A: What certifications or approvals are applicable to the E31NCFT-LNN-NS-01?
Q: What are the step characteristics of the E31NCFT-LNN-NS-01?
A: The E31NCFT-LNN-NS-01 has a step angle of 1.8 degrees, hence requiring 200 steps to complete one revolution.
