POLISI3D 5-Pack High Torque 42N.cm 3D Printer Motors Nema 17 Stepper Motor 42 Motor 1.5A 1.8 Degree 4-Lead with 1m Cable and Dupont Connector (5)

• The coil material of our motors is made of pure copper clad wire, and the copper wire is evenly arranged, so that the temperature of outgoing line will not be too high and the torque will not decline after long-term use
• Good Functions: The surface of rotor is coated with imported epoxy resin adhesive to eliminate the burr on the rotor surface. The magnetic field of the motor is more stable, the torque is larger than that of similar products, and the motor runs more smoothly and stably with lower noise and longer service life
• Warm Noice: Make sure the motor connect to a constant current or chopper drive controller before you test motor. Connecting the motor directly to a power supply will destroy the motor.
• Package: 5pieces 40mm height nema 17 motor with 5 pieces cable with dupont connector
• International products have separate terms, are sold from abroad and may differ from local products, including fit, age ratings, and language of product, labeling or instructions.
