Discussion Overview
The discussion revolves around wiring a motor switch for a new motor installation on a Logan lathe. Participants explore the specifics of connecting a reversing switch and ensuring proper electrical connections, including considerations for voltage and grounding.
Discussion Character
- Technical explanation
- Debate/contested
- Experimental/applied
Main Points Raised
- One participant describes the existing wiring of the old motor and seeks assistance with the new motor's wiring, specifically regarding the reversing switch.
- Another participant suggests identifying the supply voltage, asking if it is closer to 115V or 230V.
- The original poster clarifies that both 120V and 220V are available, but the old motor operated at 120V.
- A participant proposes connecting the neutral of the 120V supply to T5 of the new motor, indicating that the reversing switch will handle the T6-T8 swap.
- Another participant confirms the connection of Line1 to T5 and suggests following a specific wiring diagram for the remaining connections.
- The original poster reports successful testing of the wiring setup, noting adjustments made to terminal connections for correct motor rotation.
- A participant emphasizes the importance of connecting the protective earth to both the motor casing and lathe chassis, while humorously acknowledging a previous mistake regarding rotation direction.
- Another participant agrees on the grounding issue and reflects on the learning experience regarding motor rotation direction.
- The original poster concludes that the new motor and drum switch are functioning properly after installation.
Areas of Agreement / Disagreement
Participants generally agree on the wiring approach and the importance of grounding, but there are variations in specific wiring details and the interpretation of motor rotation direction.
Contextual Notes
The discussion includes assumptions about the wiring configuration and the specific motor model, which may not be universally applicable. There are also references to personal experiences that may influence the advice given.
