82JX1200K/80ZY125 82mm 120N.m Permanent Magnet DC Brushed Planetary Gear Motor

The permanent magnet DC planetary gear motor is designed with 12V/24V dual voltage compatibility to adapt to different energy consumption scenarios. The no-load speed of 2000-3500 rpm and the 6-71 transmission ratio can accurately adjust the output torque (up to 120N.m) and speed to meet the power requirements from precision instruments to heavy-duty equipment. The combination of motor inertia of 274-440 kg·cm² and peak torque of 4.4N.m ensures the impact resistance of sudden loads while responding quickly with low inertia (start and stop <3ms). The no-load energy consumption of static current of 22-30mA highlights the high efficiency of the electromagnetic system.

The reduction system adopts a multi-tooth meshing metal planetary gear structure, and realizes low-noise operation through load-sharing design, ensuring the durability of the gearbox in harsh environments such as dust and humidity. The combination of compact metal chassis (length 24mm) and 120N.m torque density enables it to balance the conflicting requirements of high power output and system integration in space-constrained scenarios such as automated production lines and medical equipment.

The overall parameter system points to the dual standards of industrial-grade reliability and dynamic control accuracy. It is particularly suitable for servo drive scenarios that require fast start and stop, high torque density and environmental tolerance, such as core power units in robot joints, precision turntables and other fields.
