W-L02787 Robot Axis-1 Servo Motor

Original OTC DAIHEN Robot Axis-1 Servo Motor W-L02787

OTC DAIHEN W-L02787 Servo Motor (OEM Motor Model: R2AA10075GCPDO) is the core powertrain custom-engineered for OTC DAIHEN high-end industrial robots. Rated at 750W, this motor is specifically built to endure high-frequency forward/reverse rotation and massive rotational inertia on Axis 1 (base rotation axis), serving as the standard actuator on mainstream FD series models including the FD-B6 and FD-V8. Utilizing premium permanent magnet synchronous technology, it acts as the electrical heart ensuring overall robotic trajectory accuracy and long-term operational uptime.

🔧 Mounting Position & Heavy-Load Powertrain Performance

Axis 1 (the base axis) of an industrial robot supports the total weight of the entire mechanical arm structure and tooling payload, generating massive inertia shocks during high-speed rotational braking. The W-L02787 servo motor delivers exceptional instantaneous overload capacity (peak torque exceeds 3x the rated value). Working in tandem with the reduction gear, it guarantees millimeter-level emergency stop precision and smooth acceleration under full-payload, maximum-velocity operation.

🌟 Core Technical Advantages & Specifications

• 100% Genuine Japanese OEM Component: Built by OTC DAIHEN in Japan, guaranteeing seamless protocol compatibility with control cabinet servo amplifiers without communication faults or driver errors.
• High-Resolution Absolute Value Encoder: Integrated industrial-grade absolute encoder retains positional memory permanently during power outages. When rebooting after unexpected power loss, the robot resumes operation immediately without requiring manual zero-point calibration (zeroing).
• Rigorous Active Thermal & Overload Defense: The motor interior embeds highly sensitive PTC thermal and overcurrent detection feedback loops. In the event of severe mechanical jamming, it instantly transmits stop signals to the motherboard, preventing coil burn-out.

🔍 Nameplate Identification & Maintenance Guidelines

As shown above, always verify nameplate data on the faulty motor before ordering. Physical nameplates typically display the OTC order part number (such as W-L02787A, where the trailing letter denotes production batch and does not affect mounting or electrical compatibility) alongside the OEM motor model (R2AA10075GCPDO).
Maintenance Tip: Axis-1 motors operate near workshop floors surrounded by conductive dust and welding spatter. If you encounter mechanical brake release anomalies or encoder communication faults, inspect motor tail power and encoder connectors for looseness, fluid ingress, or pin damage before attempting to dismantle the motor body, protecting factory dynamic balance seals.
