Product: Screw-drive motor with M8 double-threaded shaft, reversible, adjustable speed, self-braking, for 12 V or 24 V DC Key benefits - Precise linear control: the screw-drive design and M8 double-threaded shaft convert rotary motion to smooth, accurate linear movement—ideal where controlled travel and position repeatability matter. - Safe holding without extra hardware: built-in self-braking holds position when power is removed, preventing drift or backdrive and reducing the need for external brakes or locking mechanisms. - Flexible integration: reversible rotation and adjustable speed let you tailor direction and rate to the application; compatible with standard 12 V and 24 V DC systems. - Predictable performance: rated speed examples and range allow you to design to expected duty cycles and travel times (see specifications). What it does and how it solves problems - Converts motor rotation into linear motion via an M8 double-threaded shaft, providing smooth, low-backlash travel for actuators, positioning stages, or clamping mechanisms. - Self-braking capability prevents unintended movement when power is off, improving safety and reducing additional component costs. - Reversible operation allows bidirectional control without mechanical reversing gear. - Adjustable speed gives you control over acceleration, travel time, and force application, enabling both fast cycles and precise slow movement as needed. Specifications and important attributes - Drive type: screw-drive motor (screw to nut linear conversion) - Shaft: M8 double-threaded (M8 size, double thread for smooth engagement) - Speed: adjustable; approximately 12–470 U/min (rpm) depending on supply and load. Example: 160 RPM at 12 V under nominal conditions. - Voltage: compatible with 12 V DC or 24 V DC systems - Direction: reversible (can run clockwise or counterclockwise) - Braking: self-braking (holds position when power is removed) Compatibility and installation notes - Mechanical interface: M8 double-threaded shaft mates with M8 nuts or threaded fittings; verify thread direction and pitch when replacing or integrating with existing hardware. - Electrical: designed for 12 V or 24 V DC supply—confirm controller or power source matches voltage and current requirements for desired speed and torque. - Control: speed and direction can be adjusted via compatible motor controllers, PWM drivers, or reversible switch arrangements; ensure driver supports self-braking characteristic. Practical use scenarios - Linear actuator for small lift or tilt mechanisms: drive an M8 nut along the shaft to raise/lower panels, supports, or fixtures with predictable travel and secure holding at power-off. - Automated clamp or vise: use the self-braking feature to maintain clamping force without continuous power, reducing heat and energy consumption. - Positioning stage or small conveyor adjustment: reversible and speed-adjustable motion enables precise positioning and controlled indexing for light-duty material handling or assembly tasks. Why choose this unit - Combines common DC compatibility (12 V/24 V) with an M8 double-threaded shaft for straightforward mechanical integration. - Built-in self-braking reduces system complexity and improves safety. - Adjustable speed and reversible drive provide application flexibility without extra mechanical components. Note: Match motor speed and torque to load and duty cycle during design. Verify electrical control method is suitable for the listed voltages and the self-braking characteristic.
