WCHG-200-200A by Okuma

The Okuma WCHG-200-200A is a robust spindle motor in the WCHG Winding Changeover Spindle Motors series designed to streamline winding changeover operations in industrial automation environments. With a voltage range of 24V DC to 48V DC and a continuous current of 40A, this motor delivers consistent torque for extended production cycles. Its natural convection cooling system reliably dissipates heat without auxiliary fans or complex coolant circuits, ensuring stable operation even under variable loads.

Building on these foundational characteristics, the WCHG-200-200A offers a peak current of 73A for short-duration high-demand tasks, maximizing performance when rapid acceleration or load shifts occur. Feedback accuracy is provided by an incremental encoder with Hall sensors, facilitating precise position and speed control. Communication is streamlined through dual RS232 and RS485 interfaces, enabling seamless integration with PLCs, CNC controllers, and other automation hardware. This flexible interfacing supports a range of command protocols and data rates, allowing for custom configuration without additional hardware.

Protected by a Protection Class IP20 rating, the motor’s enclosure safeguards internal components from solid contaminants, while its convection-based cooling promotes sustained thermal stability over long duty cycles. Though not rated for water ingress, its simplicity reduces maintenance points and enhances mean time between failures. In industrial applications, the WCHG-200-200A provides reliable winding changeover performance, improved process uptime, and streamlined system architecture—delivering tangible gains in efficiency, durability, and overall productivity.
