Specialty Motors and Innovative Solutions
Lin Engineering's specialty motors are designed and manufactured to deliver optimized performance and/or to satisfy specific applications
Motors capable of withstanding extreme environments

These motors are designed and manufactured to operate in unique environments for specific applications. Vacuum-rated motors, for example, are perfect for environments where out-gassing needs to be minimized, which includes vacuum chambers, space applications, and clean room environments. IP (Ingress Protection) rated motors are perfect for applications exposed to humidity, water, oil, and other various debris. We also carry motors that are specifically designed to operate in extreme hot and cold temperatures.
- Vacuum and UHV grade Motors – 10E-7 Torr
- Ingress Protection (IP) Rated Motors – IP67
- Hot/Cold temperature operating Motors – 80°C to 135°C
Geartrain Integrated Motors

Motors with an integrated gearbox can save up to 50% overall length when compared to a conventional gearmotor with standard mounting, allowing them to fit in places a typical geared motor could not. This allows smaller and more powerful motors to be used in applications with a certain size constraint. The geartrain integrated motors come in a variety of sizes and gear ratios. For example, our integrated geartrain NEMA 17 motor measures just 26mm in length while providing 63.5 N-cm (90 oz-in) of holding torque.
Key Benefits:
- Ultra slim design
- As thin as 26mm in overall length
Slim Design Motor Family

In many applications, reducing the overall length is very key: smaller components normally translate to an overall smaller device which is always a benefit.
Over the years, we have developed a number of different motor options with just that in mind: reducing overall length without sacrificing a lot of performance.
The motors below are available in both NEMA 14 (36mm) and NEMA 17 (42mm) mounting options and come in a variety of shapes and sizes.
Key Benefits:
- Ultra slim design
- As thin as 12.5mm in overall length
- Ranging from NEMA 14 (36mm) to NEMA 17 (42mm) mounting options
Smooth Movement Spectrum

As conventional steppers accelerate, they can run into different resonance zones which tend to result in unwanted vibration. These motors are designed to deliver smooth movement with little to no resonance at both slow and high-speed operation.
Key Benefits:
- Low resonance and overall vibration
- Lower detent torque
- Different sizes and step angles are available
Thermally Optimized Design

Our thermally optimized motors are designed to generate less heat than a conventional motor by up to 30% while delivering similar torque output. Thermally optimized motors lower power consumption, and lower operating energy costs. Additionally, motors can be safely overdriven to temporarily increase torque output by up to 20%. Thermally optimized motors are ideal for applications that are sensitive to heat generation or require increased operating efficiency.
- Up to 30 percent cooler operation
- Lower power consumption
- Lower operating energy cost
- Over-drivable for up to 20 percent increased torque
Enhanced Power Density Motors


Lin Engineering patented Enhanced Motor technology provides 40% more torque across the entire speed range of the motor without increasing the drive voltage or current. This is due to higher motor efficiency and power density. Additionally, enhanced motors can provide the performance of a standard motor while reducing the power draw, often reducing the cost of driver/electronics; or reducing the frame size of the motor while maintaining performance. Enhanced motors can also run at a higher speed than conventional motors and operate at a lower temperature.
- Patented Enhanced Motor technology
- 40% more torque without increasing voltage or current
- Achieve higher speed than conventional motor
- Reduce the motor size
- Lower the cost of driver/electronics
Miniature Size Design in Fractional INCH

One of the biggest problems Engineers face while designing ever-smaller devices is having sufficient power in the smaller package. As the size of equipment decreases, the demand for smaller motors increases. However, oftentimes small enough motors simply don’t exist, and if they do, they do not provide enough torque or speed to be useful in the application. Often, the only option is to use a large framed motor and shrink everything else around it.
Lin Engineering solves these problems by designing innovative and capable motors that can be measured in fractional inches. Including the most powerful NEMA 6 motor on the market, as well as brand new HPM technology motors.
Large Hollow Shaft

Conventional stepper motors cannot accommodate large diameter shafts without sacrificing torque and performance. Torque is dependent on the size of the magnet placed in the rotor. Therefore, a large diameter shaft reduces the space available for the magnet, thus sacrificing torque. With the unique design of our Z series motors, we can accommodate a large shaft, up to 11mm ID, without sacrificing the motor’s torque or performance.
- Hollow Shaft up to 11mm in diameter
- No Torque Loss Due to Large Hollow Bore
- Smooth and Quiet Operation
