Product Description:
POWERMAX II P Series Hybrid Steppers set the performance standards in the world for NEMA 23 step motors. With the holding torque of up to 253 oz-in., you cannot find a 2-inch step motor that is more powerful anywhere on the globe. These hybrid step motors are designed for manufacturability. Standard POWERMAX II motors come in half, 1 and 2 stacks, which provides 42 to 253 oz-in holding torques. The P21NRLC-LSS-NS-03 is one of the best motors in the P Series POWERMAX II. These hybrid steppers come with the best features and benefits for you as the end-user.
The P Series POWERMAX II features a Warranty of 1 year, which ensures reliable, high-quality operation. The POWERMAX II motors have exceptional thermal dissipation because of the featured new polymer encapsulated stator. Because these hybrid stepper motors have larger 30mm bearings, the life span increases by 4 times that of 22 mm or smaller bearings used on similar motors of 23 NEMA size. The bearing fatigue life (L10) of the POWERMAX II P Series motors goes beyond 10,000 hours at any rotational speed. It goes up to 10,000 full steps per second if you operate it within the maximum radial and axial loads.
The P21NRLC-LSS-NS-03 comes with a number of technical specifications that make it the first choice in the market. This hybrid step motor features a NEMA Mounting with a NEMA 23 size. It comes with a single stack and winding type of per assigned letter. The P21NRLC-LSS-NS-03 has an encoder option of no feedback as well as factory assigned termination and sequence number. This motor also has Special Shaft Configuration and Shaft Modifications.
Frequently Asked Questions about P21NRLC-LSS-NS-03:
Q: What is the benefit of improved thermal dissipation?
A: Improved thermal dissipation reduces downtime and increases motor life.
Q: Which motor features helps thermal dissipation?
A: Exposed lamination aids help thermal dissipation.
Q: What are the holding torque ratings?
A: The holding torque is 0.82 Nm for series and parallel connections and 0.58 Nm for unipolar connections.
Q: What are the current ratings?
A: The current rating is 3.5 Amps for parallel connections, 1.75 Amps for series connections, and 2.5 Amps for unipolar connections.
Q: What is the benefit of oversized 30 mm bearings?
A: Oversized 30 mm bearings increase fatigue life by four orders of magnitude.
