How Medical Motors with PM Synchronous Motor Technology Enhance the Healthcare Industry

Permanent Magnet Synchronous Motors (PMSMs) are electric motors that use permanent magnets to create a constant magnetic field. PM motors are known for their high efficiency and precise control, which are crucial for medical applications.

Torque motors and Moving Magnet Actuators (MMAs) are specialized designs that Magnetic Innovations has developed. Our PM motors are characterized by low cogging values, high torque and a high accuracy. This results in smooth operations and further enhancement of medical equipment.

High-Torque Medical Motors for Advanced Medical Applications

High-torque PM synchronous motors are particularly valuable in applications requiring robust and reliable performance. In the medical field, high torque is essential for devices such as surgical robots, automated drug delivery systems, and diagnostic imaging equipment.

Both brushless inrunner and outrunner configurations of torque motors are available at Magnetic Innovations. They meet the diverse needs of applications in the medical industry, each with unique benefits. Inrunner torque motors provide higher speed, while outrunner motors deliver greater torque in a compact design. Other advantages of our High Torque motor series are:

• Enhanced Precision and Control: Medical motors like high-torque PM synchronous motors offer exceptional accuracy in controlling the speed and position of medical devices, which is crucial for equipment such as MRI machines and robotic surgery tools.
• Energy Efficiency: High-torque motors consume less energy compared to traditional motors, helping healthcare facilities reduce operational costs and meet sustainability goals.
• Compact Design: The compact size of PM synchronous motors allows for smaller, more ergonomic medical devices, improving usability for healthcare professionals.
• Low Cogging: Our motors exhibit low cogging, resulting in smooth and uniform rotation. This reduces vibrations and minimizes noise, which is particularly advantageous in the medical field.

Moving Magnet Actuator for Medical Equipment

Moving Magnet Actuators (MMA’s) are Single-Phase DC Linear Motors that offer unique advantages for medical equipment. These type of electrical actuators provide smooth linear motion with direct drive technology and low power.

The MMA’s can push or pull a component in a straight line with high precision and minimal mechanical noise. The actuator’s direct-drive design means there are no gears or belts involved, resulting in a clean and efficient motion that is ideal for applications requiring accurate and controlled movements. Advantages of the MMA are:

• Enhanced Performance: MMA’s provide smoother motion and higher precision, making them ideal for applications that require accurate positioning.
• Reduced Maintenance: With fewer moving parts compared to traditional actuators, MMAs experience less wear and tear. Resulting in lower maintenance requirements and a longer lifespan for medical equipment.
• Compact and Lightweight Design: The streamlined design of MMA’s makes it possible to create more compact and lightweight medical devices.
• High Reliability: MMAs are highly reliable and durable due to their lack of moving wires and mechanical components, which minimizes the risk of failure and ensures long-term lifespan.
• Improved Thermal Path: Thanks to the direct-drive design of MMA’s, they provides a better thermal path, which helps prevent overheating of the coil and enhances force density.
