Machine builders and automation engineers often face a frustrating constraint: linear actuator manufacturers locking them into proprietary, single-source motor and drive platforms. At TOYO Robotics, we take an open-architecture approach. Much like the industry's popular "Your Motor Here" philosophy, TOYO electric linear actuators are designed from the ground up to pair seamlessly with your preferred third-party servo and stepper motor brands.
Whether your facility has standardized on Rockwell Automation (Allen-Bradley), Mitsubishi Electric, Yaskawa, Panasonic, Delta, Oriental Motor, or standard NEMA-frame stepper motors, TOYO delivers factory-engineered motor mounting kits, precision couplings, and custom intermediate flanges to get your machine running without compromise.

Why Choose TOYO's Open Motor Architecture?
Standardizing on a single control and drive architecture across your entire production plant delivers substantial operational advantages:
- Zero Control Re-Engineering: Maintain your existing PLC architectures, motion controllers, communication protocols (EtherNet/IP, EtherCAT, PROFINET, CC-Link), and drive programming routines.
- Reduced Spare Parts Inventory: Avoid the overhead and complexity of stocking proprietary spare motors, specialized cables, and replacement drive amplifiers.
- Fast Mechanical Adaptation: Pre-machined motor adapter plates and zero-backlash flexible couplings ensure rigid, precise power transmission with straightforward drop-in installation.
- Flexible Motor Orientations: Choose between direct-drive inline mounting, left/right parallel wrap configurations, or under-slung brackets to fit tight machine footprints.
