GM25-30 DC Telescopic Rotary Gear Motor 3V/6V/12V

GM25-30 Micro DC Gear Motor, Telescopic Rotary Linear Actuator, Low-Speed Thrust Motor, 3V/6V/12V

Product Description

This is the CHR-GM25-SM30 series DC telescopic rotary gear motor, featuring a worm-driven reciprocating telescopic structure and gear reduction mechanism, delivering strong torque and reliable performance. It supports a wide operating voltage range of DC 3V-12V, with multiple options including the standard motor, encoder version, and solderless PCB version to meet diverse project needs.

Key Features

• Telescopic & Rotary Design: Completes one full telescopic cycle every 6 motor rotations, ideal for linear reciprocating motion applications.
• Multiple Configurations:
  • Standard Version: Basic structure for cost-effective use.
  • Encoder Version: Equipped with an AB-phase Hall encoder with a shielded housing, outputting high/low level square waves for speed and direction control. Built-in pull-up resistors simplify MCU programming.
  • Solderless PCB Version: Integrated with an anti-interference PCB and a PH2.0-2PIN terminal connector with a matching wire harness, allowing direct plug-and-play connection to avoid motor damage or user burns from soldering.
  
  
• High Thrust & Low Speed: Delivers stable low-speed rotation with high linear thrust (up to 60N at 12V), suitable for precision applications.
• Adjustable Stroke: Available in 20mm and 30mm telescopic lengths to fit different installation requirements.
• Reliable Build: 24mm outer diameter, compact size (105-120mm length), lightweight (approx. 75g), and a 5x5 square drive shaft for secure connection.

Specifications (Typical)

• Operating Voltage: DC 3V~12V
• Rated Speed (12V): 330±10% RPM
• Rated Torque (12V): 1.0 Kg·cm
• Stall Torque (12V): ≥3.0 Kg·cm
• Max Thrust (12V): ≤60N
• Gear Ratio: 1:19 (18.837)
• Stroke: 20mm / 30mm
• Weight: Approx. 75g

Applications

Perfect for small robots, smart home appliances, educational toys, automation projects, and other applications requiring linear reciprocating motion.

Note: Avoid frequent stall operation, frequent start-stop, and forward/reverse switching, as these can significantly shorten the motor's service life.
