Description
These motors possess exceptional radiation resistance; their core components undergo special anti-radiation modification, enabling them to withstand high-energy radiation doses of up to 1×10⁶ Gy over extended periods. This effectively protects the motor coils and circuitry from radiation damage, ensuring long-term stable operation. Additionally, these motors are designed for a wide temperature range of -196°C to +200°C, enabling them to withstand temperature fluctuations during waste processing without experiencing performance degradation or structural damage due to alternating high and low temperatures. The radiation-hardened clean stepper motor is equipped with flanges in multiple sizes (28/42/57/86 mm) and offers a torque range of 0.04–6 Nm, meeting the drive requirements for various loads such as waste transfer, valve control, and detection equipment. The irradiation-clean stepper motor delivers stable torque output, ensuring smooth operation during the waste treatment process, while its multi-size design enhances compatibility with nuclear industry equipment.
Nuclear waste processing demands extremely high standards for equipment cleanliness and safety. The irradiation-clean stepper motor features a fully sealed design that effectively prevents radioactive dust from entering the motor interior while also preventing impurities generated by wear on internal components, thereby ensuring a clean operating environment. To meet the automation needs of the nuclear industry, radiation-resistant clean stepper motors support functional options such as dual-axis control, position feedback, and safety braking, enabling precise positioning and safe start/stop operations to enhance operational safety and efficiency. These motors deliver stable power output in applications such as waste transfer robotic arms, vacuum-sealed valves, and radioactive detection equipment; in high-radiation work areas, they maintain low failure rates and long service life. With their superior radiation resistance and cleanliness characteristics, radiation-resistant clean stepper motors provide safe, stable, and reliable power support for nuclear waste processing. They also contribute to the safe and efficient development of the nuclear industry, making them the preferred choice for drive equipment in the sector.
