42JX150K/42STH 80N Hybrid Planetary Gear Stepper Motor

42JX150K/42STH Hybrid Stepping Planetary Gear Motor is a high-performance hybrid stepping motor that combines the advantages of a planetary gear reducer, suitable for applications requiring high precision and high torque output. The motor uses a metal ring gear material to ensure stability and durability under high load conditions. Its maximum allowable radial load is 80N, the maximum allowable axial load is 30N, the radial play is only 0.06mm, and the axial play is 0.3mm, with a backlash less than 1.5° when unloaded. These parameters indicate that the motor has mechanical performance and precise motion control capabilities. Additionally, the motor offers various specifications, including different voltage, current, resistance, inductance electrical parameters, as well as multiple reduction ratios and gear stages, to meet the needs of different application scenarios. Through optimized design and high-quality manufacturing processes, this motor excels in efficiency, reliability, and service life, making it an ideal choice for industrial automation, precision instruments, and robotics technology fields.
