High Precision Motion Control Electric Servo Strain Wave Actuator HAT-58

The large hollow bore rotary actuator typically integrates an internal frameless torque motor with components such as a harmonic drive reducer, an absolute encoder, and a customized large hollow bore harmonic drive unit to form a complete rotary actuator assembly. Its control unit (drive system) is typically externally mounted, allowing for high-precision motion control of connected equipment. Compared to standard rotary actuators, this series features a larger hollow bore diameter, allowing passage of lead screws, cables, and other components. It is designed for applications that require an ample through-bore space, high precision, and compact integration, such as machine tool rotary tables, precision medical devices, 5-axis laser cutting systems, and semiconductor equipment.

Features

  • Structural Characteristics: Modular design integrating high-precision encoders and intelligent power modules (IPM), offering compact size and strong EMI resistance.
  • Supports multiple control modes (position/speed/torque) and is compatible with both AC permanent magnet synchronous motors and DC servo motors.
  • Control Algorithm: Vector-based triple-loop control (current/speed/position) optimizes dynamic response accuracy and stability.
  • Implements complex control logic via digital signal processors (DSPs), supporting networked communication and remote debugging.
  • Performance Highlights: Micron-level positioning: High-resolution encoder feedback eliminates cumulative errors, achieving sub-micron repeatability.
  • Rapid response: A low electromechanical time constant enables millisecond-level start/stop or direction reversal, making it ideal for high-frequency motion.
  • Wide speed range: Supports low-speed, high-torque, and high-speed, light-load operation, with a speed ratio exceeding 1:5000.
  • Adaptability: Compatible with standard interfaces (e.g., EtherCAT, CANopen) for seamless PLC/system integration.
  • Built-in soft-start circuits and overvoltage/overcurrent protection reduce startup surges and failure risks.

Shipping Policy

To minimize or avoid tariffs, we ship from the country where the product is made, such as China, Italy, or Taiwan. We sell worldwide in USD.

Fast Delivery! We ship via FedEx, UPS, DHL, and USPS because they're fast, reliable, and easy to track. We process orders within 24 hours, and delivery may take 4-7 working days, depending on your location. We'll email you the tracking number once your order is shipped. We sell in USD.

Shipping Costs: For some industrial products, such as heavy wheels and CNC machines, we calculate shipping costs by weight rather than quantity. To reduce shipping costs for orders with multiple items, please email us at sales@ozrobotics.com before placing your order. We show shipping rates on the product page under the SHIPPING tab. To view the shipping cost for your country, click 'Add to Cart' on the product page.

Return Policy

5 Hours: Mistakes happen when ordering, so you have 5 hours to request a refund for any reason, including if you don’t want to pay the tariff. However, Stripe will not refund you their processing fee if you cancel your order.

All Sales Are Final: After 5 hours, we cannot cancel your order or issue a refund because order cancellations incur multiple transaction processing fees from Stripe and PayPal, additional shipping fees, and reverse tariff payments, which are costly and time-consuming. For technical issues, we will be happy to assist you in resolving problems and provide a replacement if you can prove that the product has a manufacturing defect.

Exchange Policy: We want you to be happy with your new purchase. However, once you have used the product, we cannot issue a refund. However, we will offer an exchange for a product with irreversible manufacturing defects or technical issues. If you purchased the wrong product, then you, as the customer, will be responsible for the re-shipping fees and tariffs. If the product you purchased is defective, email us at support@ozrobotics.com with photos or a video of the faulty parts so we can evaluate the issue before arranging a replacement.

Terms and Conditions

If you were not at home or at your shipping address during the parcel delivery: It is not our or the supplier's fault; if the shipping/delivery company could not deliver your parcel because you, the customer, were not at home or at your delivery address on the delivery date/time, and as a result, the carrier returned your parcel to the manufacturer from where it was shipped. Please note that we do not accept excuses; you will therefore have to pay the re-shipping fee and the tariff for any re-shipment request. In such a case, we will not issue a refund. Please always check your spam folder to ensure you receive emails from Oz Robotics and shipping companies.

Product Warranty: Our warranty covers only product-related problems caused by manufacturing defects. It does not cover problems resulting from faulty repair attempts, customer accidents, or misuse.

Please check your SPAM folder! To provide you with delivery information, we may add your email address to the shipping website so you are notified of delivery until your parcel reaches your shipping address. Please always check your spam folder to ensure our emails from ozrobotics.com and email notifications from DHL, UPS, FedEx, USPS, or other couriers don't land there. Please let us know if you don’t want us to enter your email address on the shipping company website for event notifications.

We’re here to help you buy the hottest products affordably, with fast shipping and World-Class Customer Support. However, please review the newly imposed tariffs and click the Delivery tab to read our Return and Refund policies before making a purchase. We sell in USD. We Sell Worldwide.

Tariff: To minimize or avoid tariffs, we ship from the country where the product is made, such as China, Italy, or Taiwan. Since we don’t always ship products to you from the USA (except for products made in the USA or stocked), you won’t be affected by the new tariffs imposed by the USA. Due to new tariff agreements, not all products are subject to tariffs, as tariffs vary by country and product. For example, customers in the USA will pay a tariff on products imported from China, based on the tariff rate agreed between the USA and China. If applicable, you will pay the tariff in your country. The total amount of your order does not include a tariff, which you’ll pay before the delivery. We will not issue a refund if you don’t pay the tariff.

Tariff vs. Shipping Fee: Please don’t confuse the shipping fee with the tariff, because they are two separate charges. You pay us a shipping fee for the carrier to deliver your order to your door. You pay the tariff to the customs office, a branch of your government, as an import tax.

Why aren’t we adding tariffs to the product’s retail price? If all countries imposed the same tariff amount and used the same currency, we would have added that tariff to the product’s retail price. Our suppliers and we are not responsible for tariffs. Please shop accordingly.

Ships From: On this product page, check the Ships From: label to see which country the product ships from. We do not ship all products from the USA; some products ship from regions such as China, Taiwan, Canada, and Europe. Therefore, the tariff you pay depends on the country of origin, as not all countries charge the same rate. For example, suppose the US imposes a 30% tariff on goods imported from China; in contrast, other countries may impose a significantly lower tariff, or even none at all, on goods shipped from China into their countries.

Attention! We will email you the tracking number so you can follow your parcel. The shipping company will contact you by phone, text, or email to arrange payment of the tariff. However, as the customer, you are responsible for responding to their calls, texts, or emails. You can also use the tracking number link we emailed you to contact the shipping company and pay any applicable tariffs, if you haven’t already.

Heads Up! We’re not responsible if the shipping company returns your parcel to the country of origin due to the unpaid tariff or non-compliance with its requirements. As a result, you will be responsible for reshipping costs and applicable tariffs. We will not accept any excuses for failing to follow up with the shipping company regarding the tariff, and we will not issue a refund.

Please check your SPAM folder! To provide you with delivery information, we will add your email address to the shipping website so you are notified of delivery until your parcel reaches your shipping address. Please always check your spam folder to ensure our emails from ozrobotics.com and email notifications from DHL, UPS, FedEx, USPS, or other couriers don’t land there.
