The HPJM series is a DC servo drive system that provides high torque and precise rotational movement. It integrates precision control gear reducers (harmonic gear reducers) from sizes 05 to 40 with flat DC servo motors from sizes 30 to 132, forming a robot-integrated joint motor (also known as a joint module).
The matching reducers are available in two types: harmonic gear series and planetary gear series.
Key Features:
Compact Design: The outer diameter has been reduced, and the maximum torque-to-volume ratio has been increased to approximately twice that of conventional products. The hollow structure maintains the same dimensions as previous models, with a through-hole at the center of the drive unit allowing for wiring, piping, or laser passes, providing energy or transmitting signals to moving mechanical parts or devices.
Increased Torque and Precision: With a hollow through-hole design, the torque is approximately 30% higher, offering greater precision, stiffness, and quieter operation.
Ideal for Advanced Applications: This system is suitable for humanoid robots, exoskeletons, collaborative robots, and other high-end application scenarios.
Enhanced Torque-to-Volume Ratio: The series integrates high-torque precision control reducers (harmonic gear series or KH planetary gear series), reducing the outer diameter by approximately 20% compared to previous products, while increasing the maximum torque-to-volume ratio to around twice that of previous models.
Large and Diverse Product Range: The harmonic PRO series includes 22 models, with high-torque variants up to 1450 N·m, as well as 11 models in the harmonic hollow-through-hole series. Gear ratios available include 1/51, 1/81, 1/101, 1/121, and 1/161, providing a rich variety of models.
Modular Design: The HPJM series uses a basic modular design that combines reducers, output bearings, motors, brakes, encoders, and other components. Custom models can also be provided upon customer request; please consult the sales department for more details.
Standard 17-bit Magnetic Absolute Position Encoder: The newly developed DC servo motor is equipped with an in-house designed, highly reliable, safety-functional 17-bit magnetic absolute position (absolute value) encoder. Using serial communication saves on wiring, and, in addition to the essential rotational count functionality required for devices with reducers, the encoder can retain the absolute position even when the cable is briefly disconnected.
Fault Safety: The encoder compares the angle of two systems continuously, and built-in fault detection provides safety protection by outputting any sudden faults to the upper-level system, aiding in the construction of a safety system.
Support for High Speed: When used in combination with the hollow planetary gear reducer KH series, it can also support higher speeds.
Our robot joint motors are suitable for humanoid robots, exoskeletons, collaborative robots, automobiles, AGVs and other application scenarios.
