Quantum Devices Commutating Encoder Product Delivers for OEM Medical Application
November 9, 2020
When a longstanding OEM customer needed an encoder product for their medical equipment application they turned to Quantum Devices and one of their commutating optical rotary encoders.
When it comes to medical applications, customers demand a level of accuracy and a higher tolerance to motor shaft misalignments. A large health care company depended on our OEM customer, a motor manufacturer, to deliver on these requirements. Having commutation included with the encoder reduces motor costs, by removing hall effect sensors and reducing the magnet volume from the motor. Commutation also reduces the number of cables/conductors mating the motor assembly to the drive.
Why Quantum Devices Commutating Encoder Products Fit the Bill
The end product, a blood separation centrifuge, needs accurate acceleration control, the ability to precisely maintain speed and also requires very accurate stopping positions. With their low profile assembled heights down to 0.43”—and both bearinged and bearingless encoder designs, Quantum Devices’ encoders provide the high-performance and operating precision needed. With resolutions from 24 to 5000 physical lines per revolution and up to 20,000 interpolated pulses (or 80,000 quadrature edges), their encoder products deliver accuracy across the entire performance spectrum required for this separation mechanism.
How Quantum Devices Delivers Quality Encoders for Medical Field
- 48-hour turnaround time for web store product samples – Quantum Devices recognizes the need in medical applications for quick samples which are consistent with production units. For this reason, prototype sample encoders are manufactured to the same standards and on the same manufacturing lines as production units. Quantum Devices is able to rapidly manufacture prototype encoders by leveraging a vast inventory of raw components as well as a vertically integrated supply chain. Manufacturing time has been reduced to 48 hours for several encoder products which are available for purchase directly from the Quantum Devices web store.
- No Firmware in encoders – Virtually all Quantum Devices’ encoders – including the QR12, LP12, QR145, QM22, QM35 and QML35 optical encoders – contain no Firmware. In a highly regulated industry, the introduction of Firmware creates a potential for failure that is a real concern in medical applications. Firmware often creates certification issues for medical devices since it can be accidentally modified by EMI/RFI events. Unlike other manufacturers, Quantum Devices appreciates the potential corruption downside of onboard Firmware programs. Customers trust Quantum Devices: “We’ve used your encoder product before, can we use it again?”
- Dependable in medical audits – Quantum Devices customers know that the company welcomes medical audits. Their company and production process follows all necessary practices and procedures.
