Ethercat Can Protocol Harmonic Drive Precision Drive Motor

In terms of communication speed, the maximum rate of the CAN protocol is 1 Mbps. This speed meets basic requirements in small to medium-scale applications but reveals performance bottlenecks when dealing with multi-motor coordinated control. For instance, in an application with 10 motors, the CAN communication cycle typically operates around 500 Hz. However, influenced by factors such as communication content complexity and packet transmission uniformity, this cycle cannot be guaranteed stable. It may fluctuate, thereby affecting the motion synchronization of harmonic drive motors.

Furthermore, the CAN protocol employs a “Carrier Sense Multiple Access with Collision Detection” (CSMA/CD) mechanism. As the number of devices on the bus increases, the probability of data transmission collisions rises. This not only extends the communication cycle but may also lead to data loss, posing certain operational risks for harmonic drive motors that require precise control. In terms of wiring and cost, while CAN supports a bus topology that simplifies wiring, its transmission distance is limited at high speeds (typically not exceeding 40 meters). If covering an extensive robotic system requires additional repeater devices, the overall cost may conversely increase.

Features

  • Superior precision and zero backlash
  • High Precision and Zero Backlash
  • Zero-backlash design eliminates transmission clearance of traditional reducers, achieving repeat positioning accuracy of ±10 arcsec and absolute positioning accuracy of ±30 arcsec, suitable for precision motion control scenarios (e.g., surgical robots, collaborative robotic arms).
  • 3D Conjugate Dual-Arc Tooth Profile Technology
  • Optimizes tooth profile structure, reduces vibration and noise, improves transmission stiffness and service life, enabling smoother and more precise robot movements.
  • Highly Integrated, Compact, and Lightweight Design
  • Compact size and light weight: The high integration of the harmonic drive and frameless torque motor results in a compact structure, suitable for space-constrained scenarios (e.g., robot wrists, head joints).
  • Lightweight material application: Uses high-strength aluminum alloy, carbon fiber, and other materials to reduce weight and improve robot energy efficiency and flexibility.
  • High Transmission Efficiency: Transmission efficiency exceeds 80%, reducing energy loss and supporting efficient power transmission under dynamic load changes.
  • High Safety and Reliability
  • Torque sensor integration (customizable)
  • It supports collision detection and drag teaching functions, enhancing human-robot collaboration safety.
  • Impact resistance and long service life: The harmonic drive can withstand high-load emergency stops and is designed for a precision lifespan exceeding 10,000 hours, making it suitable for harsh industrial environments.
  • Intelligent Integration and Control: Embedded controller with multi-protocol compatibility: Supports communication protocols like EtherCAT and CANopen, enabling dynamic PID adjustment.
    Modular design: Standardized interfaces facilitate quick integration and maintenance.

Shipping Policy

Fast Delivery! We ship via FedEx, UPS, DHL, and USPS because they are fast, reliable, and easily trackable. We process orders within 24 hours, and delivery may take 4-7 business days after that, depending on your location. We will email you the tracking number once your order is shipped.

Shipping Costs: For some industrial products, such as heavy wheels and CNC machines, shipping costs are calculated based on product weight, not 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 require reverse tariff payments and multiple shipping fees, which are very 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. But we will offer an exchange for a product that has irreversible manufacturing defects or technical problems. 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 it before arranging for a replacement.

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

Tariff: We ship directly from the country where the product is made, such as China, Italy, or Taiwan, helping you avoid or pay lower tariffs. Since we do not always ship products to you from the USA (except for products made in the USA or stocked), you will not be affected by the new tariffs imposed by the USA. Due to new tariff agreements between countries, not all products are subject to tariffs, as tariffs vary by country or 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. And so, if applicable, you, the customer, will pay the tariff in your respective country. The total amount of your order does not include a tariff, which you will pay before the delivery. We won’t issue a refund if you don’t pay the tariff.

Tariff via DHL: Click https://www.delivery.dhl.com/on-demand-delivery.xhtml?ctrycode=US or click on the Order Tracking link we emailed to you with your tracking number. Or call DHL at 1-800-225-5345  (toll-free) or +603 7964 2800 (overseas). Contact DHL: https://mydhl.express.dhl/us/en/help-and-support.html#/contact_us. For international customers: https://ondemand.dhl.com/

Tariff via FedEx: Click the Order Tracking link in the email we sent you to view your tracking number, or call FedEx at 1-800-GoFedEx (1-800-463-3339). Or Pay here: https://www.fedex.com/en-us/shipping/international/duties-and-taxes.html.

Tariff via UPS: Click the Order Tracking link we emailed you with your tracking number, or call UPS at 1-800-742-5877.

Tariff via USPS: Click the Order Tracking link in the email we sent you to view your tracking number, or call 1-800-ASK-USPS (1-800-275-8777).

Ships From: On this product page, check the Ships From: label to see which country we will ship this product from, because we do not ship all products from the USA; some products ship from regions like China, Taiwan, Canada, and Europe. Therefore, the tariff you pay depends on the country your order is shipped from, as not all countries charge the same tariff. 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 for you to track 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 call, text, or email. You can also click the tracking number link we emailed you to contact the shipping company and make the tariff payment, if you haven’t already.

Heads Up! We’re not responsible for parcels returned to us if you don’t pay the tariff or fail to follow up with the shipping company. As a result, if the shipping company returns the parcel to its country of origin, you will be responsible for re-shipping costs and tariff charges. We will not accept any excuses for not paying the tariff or for failing to follow up with the shipping company for the tariff, and we will not issue a refund.

Why are we not 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.
