Product Description:
The Kollmorgen company is known to manufacture the best stepper motors that can be used with a wide range of industrial machines. Out of the many series of stepper motors produced by this company, the E series stands out due to its unique SIGMAX technology features that allow the stepper motor to produce higher torque and operate at a higher acceleration rates. The E21NRFA-JNN-NS-00 motor features this revolutionary technology and is able to maintain an operation efficiency as high as 90 percent even when operating at its high revolution rates. This efficiency translates to lower system and operating costs of the motor.
The E21NRFA-JNN-NS-00 works by converting direct current, from a main power source, to mechanical energy that causes the motor to move in sequential steps. These steps allows motor to operate at the high speed level that are required for rapid transverse applications or machines. The holding torque of the E21NRFA-JNN-NS-00 motor is 27.95 Newton Meters. This holding torque measures the motor at standstill and the motor when it is energized with rated DC current. The high holding torque reduces the need for additional gearing in the machine it is connected to, simplifying the overall mechanical design.
On receiving the E21NRFA-JNN-NS-00 stepper motor, it is advisable to mount in a position that does not expose it to high amounts of shocks and vibrations Operators should use the NEMA mounting process to prevent any dents or damage to the stepper motor. The E21NRFA-JNN-NS-00 stepper motor operates within a temperature range of -20 to 40 degrees Celsius. Its construction and connection style require a regular lead wire to function properly. The E21NRFA-JNN-NS-00 is a standard stepper motor without a shaft seal. To ensure the best performance of the stepper motor, following the specific mounting process and connection style is important.
Frequently Asked Questions about E21NRFA-JNN-NS-00:
Q: What type of rotor is present in this motor design?
A: The rotor present in the E21NRFA-JNN-NS-00 motor is a low inertial rotor. The low inertial characteristics is maintained even when the motor is undergoing dynamic operation.
Q: Is there any modification on the motor shaft?
A: No. The shaft present on the E21NRFA-JNN-NS-00 motor is a smooth shaft. It ensures efficient transmission of torque from the motor.
Q: How many rotor stacks are in the E21NRFA-JNN-NS-00?
A: The E21NRFA-JNN-NS-00 features only a single rotor shaft.
Q: How is excess heat dissipated from the motor?
A: The heat dissipation system of the E21NRFA-JNN-NS-00 is done through thermal radiation and natural convection.
Q: How does Wake industrial ensure the world wide delivery of the E21NRFA-JNN-NS-00 motor?
A: The worldwide delivery of this motor is done through FedEx, UPS, or DHL. This motor can be delivered to customers all over the world.
