PG45775126500-71.2K 12V DC Planetary Geared Motor
Description:
The PG45775126500-71.2K is a heavy-duty 12V DC planetary geared motor designed for high-torque industrial and robotics applications. Built with a robust 45mm planetary gearbox attached to a 44.5mm motor housing, this unit delivers a rated load torque of 53 kgf·cm at an output speed of 83 RPM. It features counter-clockwise (CCW) standard rotation, a solid 10mm keyed output shaft, and precision M4 mounting threads on a 35mm pitch circle diameter (PCD).
Key Features:
- High-Torque Planetary Gearbox: Features a 45mm reduction gearbox capable of continuous 53 kgf·cm rated torque output.
- Keyed Output Shaft: Equipped with a 10mm diameter, 27mm long output shaft featuring a 4mm keyway for secure drive coupling.
- 12V DC Efficiency: Low energy consumption with under 2.0A no-load current draw (100 RPM) and under 8.0A rated load current draw (83 RPM).
- Counter-Clockwise (CCW) Operation: Configured for default counter-clockwise output shaft rotation.
- Standard Industrial Mounting: Integrated 4x M4 threaded mounting pattern (9mm thread depth) on a 35mm bolt circle.
