Description
The PM100 is a large-diameter high-torque brushless DC motor designed for gimbals, robotic joints, rotary platforms and precision motion-control systems.
With a 24V nominal voltage, 1.6 N·m nominal torque and up to 3 N·m stall torque, the motor provides substantially higher torque than compact pancake gimbal motors while maintaining a low-profile direct-drive design.
The motor features a large center opening and is available with an AS5048A 14-bit magnetic encoder for rotor position feedback. Its 21-pole-pair configuration provides smooth low-speed operation, making it suitable for large camera gimbals, robotic arms, pan-tilt platforms and other applications requiring controlled rotary motion.
The PM100 has a 98.5mm outer diameter and a compact axial profile, allowing it to deliver high torque in applications where installation depth is limited.
