56JXS300K/57STH High Precision Hybrid Planetary Gear Stepper Motor

2JX150K/42STH High Precision Hybrid Stepping Motor Planetary Gearbox is a high-performance hybrid stepping motor equipped with a planetary gearbox featuring a metal ring gear material, suitable for various high-precision and high-torque applications. The maximum permissible radial load is 80N, the maximum permissible axial load is 30N, the radial play of the shaft is less than 0.06mm, the axial play of the shaft is less than 0.3mm, and the backlash at no-load is less than 1.5°. This motor comes in multiple specifications, such as 42STH33-0956A, 42STH33-0406A, etc., each model detailing parameters like rated voltage, current per phase, resistance per phase, inductance, holding torque, number of leads, rotor inertia, weight, and length. Additionally, performance data for different reduction ratios are provided, ranging from 3.5 to 294, with maximum rated torque from 30kg.cm to 150kg.cm, short-time permissible torque from 50kg.cm to 450kg.cm, and efficiency from 90% to 66%. These detailed technical parameters and performance indicators make this product widely applicable in industrial automation, precision machinery, and other fields.
