Features: 100% brand new and high quality High torque: high-quality motor steel material, high torque, low self-inductance, sensitive response, can avoid system errors. Low resistance: Compared with the motor of the same thickness and torque, the double tree stepper motor can obtain a lower resistance value. This greatly increases the thermal conductivity of the motor. This effectively reduces the temperature rise. Wide range of applications: This small stepper motor can be used in various fields, such as 3D printers; stage lighting; textile machinery; medical equipment; placement machines; non-standard equipment; automation equipment, etc. Uniform speed: The PCB board is strengthened in the motor, and the unique stator technology is adopted to ensure the uniform and smooth grinding of the stator teeth of the motor, the high precision of the inner hole, and the stable and accurate speed during the working process without losing steps. Stable structure: The surface of the motor rotor is coated with imported epoxy resin to seal the rotor as a whole. After high temperature curing, the rotor is not easy to process residues such as iron pins in the tooth groove after the outer circle is processed. The motor will not be stable after long-term use. Risk of jamming.
