Why this motor stands out
Designed for durability and versatile control, the AOS C-Face motor blends a compact footprint with a dual-speed capability that lets you tailor torque and speed to your machining task. The threaded shaft simplifies attachment to pulleys, couplings, or other drive components, while the 56J frame ensures compatibility with a wide range of mounting options and accessories. The 230V single-phase configuration makes it a practical drop-in upgrade for most shop power systems, reducing the need for specialized electrical work.
Ideal use cases
- Retrofits on lathes, milling machines, drill presses, and surface grinders requiring dual-speed operation.
- Direct-drive or belt-driven configurations where a robust 1.5 HP motor with predictable torque is essential.
- DIY workshop projects that demand reliable performance at both high and low speeds for threading, tapping, or material removal tasks.
Practical installation and operation tips
For a smooth upgrade, pair this motor with equipment that accepts a 56J frame and C-face mounting. The threaded shaft enables quick, secure connections to pulleys or couplings, reducing setup time. Ensure your electrical supply is configured for 230V and that wiring includes appropriate protection for a motor of this size. The two-speed design helps optimize performance: use the high-speed setting for rapid material removal and seating operations, then switch to the lower speed for finishing passes or high-torque tasks that require greater control.
What you gain with the AOS TMF-S2 motor
- Reliable, dual-speed operation that expands the range of compatible tooling and processes.
- Efficient, compact design with a familiar 56J frame that simplifies retrofits and replacements.
- Ease of mounting and integration thanks to C-face compatibility and threaded shaft.
- Clear electrical compatibility with standard 230V shop power, minimizing wiring complexity.
