Ultra-slim Profile.
High Torque, Speed, and Efficiency.
The 3618 from Lin Engineering represents a breakthrough in motor design, combining high-speed functionality with a low-profile form. This high-speed motor, paired with our slim planetary gearbox, provides substantial torque output across a broad speed range while maintaining an ultra-slim profile that sets a new standard in its class. Ideal for applications where space is at a premium but NEMA 17 performance is required, the 3618 offers the same mounting compatibility as standard NEMA 17 motors, delivering exceptional performance in a significantly smaller package. Furthermore, the 3618 is a highly efficient motor, achieving higher torque output with lower power consumption and better thermal capability compared to a standard NEMA 17 motor with similar performance.
The 3618 is versatile, allowing for compatibility with various gearboxes featuring different gear ratios—contact us for more options.
