BLDC Motors
Lin Engineering’s BLDC motors deliver smoother rotation, greater efficiency, and superior performance at high speeds, due to their use of electronic commutation. This design minimizes mechanical wear and reduces energy losses, making BLDC motors ideal for applications requiring continuous operation. Unlike steppers, which are optimized for precise positioning tasks, BLDC motors excel in high-speed, continuous-duty applications, generating less heat even during prolonged operation.

Built For Extreme Environments
High Vacuum (HV) Operation
These motors are designed to function reliably at pressures as low as 10⁻⁷ torr, making them ideal for applications where maintaining a contamination-free environment is critical. Whether used in semiconductor processing, scientific research, or other vacuum-sensitive industries, our motors deliver precision, durability, and low heat generation.
Extreme Temperature Resilience
Motors are designed to operate reliably in a wide temperature range of -50°C to +100°C (optional -70°C to 130°C), making them suitable for applications that experience extreme environmental conditions. These motors are built to handle rapid temperature cycling ensuring consistent performance and longevity. For applications requiring even broader temperature tolerance, additional provisions can be implemented to further enhance both negative and positive temperature limits.
Shock/Vibration Resilience
Motors are built to withstand both high and low amplitude vibrations, ensuring structural integrity and reliable performance. Their robust design minimizes the risk of mechanical failure or degradation, making them ideal for applications that require consistent operation under varying vibration conditions.
Low Outgassing Construction
Motors are constructed using low outgassing materials and are post-baked to ensure optimal performance in high vacuum environments. This process helps minimize the release of volatile substances, which is crucial for maintaining a clean vacuum environment. Our motors are designed to meet stringent requirements, with a CVCM (Collected Volatile Condensable Materials) value below 0.1%, ensuring minimal contamination and reliable performance in vacuum-sensitive applications.
