A practical evidence checklist for RFQ preparation and supplier evaluation.
CNFX does not score or rank suppliers. Buyers must verify all claims and documents with the legal manufacturer before ordering.
The step angle is the angular rotation per pulse. Common values are 1.8° (200 steps per revolution) and 0.9° (400 steps per revolution). The exact value is specified by the manufacturer and should be confirmed for the specific model.
Holding torque must be greater than the load torque plus a safety factor. Consider the application's load, friction, and acceleration requirements. The torque range for this product category is 0.1–12 N·m, but the actual required value depends on your system.
IP rating indicates the degree of protection against dust and water ingress. For example, IP65 offers dust-tight and water-jet protection. Choose an IP rating based on the operating environment. The range for this product is IP40–IP65, but verify the specific model's rating.
Yes, stepper motors are designed for open-loop control. The controller sends pulses, and the motor moves a precise step angle per pulse. However, if the load exceeds the motor's torque, steps may be missed, so proper sizing is essential.
