Sierramotion, a division of Allient (formerly Allied Motion Technologies), designs, builds, tests and supplies custom motors, frameless and axial flux motors, and precision motion assemblies from prototypes to volume production.
Standard frameless torque motors for direct drive and integrated precision gear drive applications. Six standard models, 38 mm to 165 mm diameter, 0.17–6.16 Nm rated torque, 12–325 VDC bus.
Standard slotless axial flux motors with zero cogging torque for low-profile applications such as cameras, gimbals and scanning systems. Seven standard models, 0.16–49.90 Nm rated torque.
Custom limited-angle, rotary, linear and voice coil motors, 8 mm to 2 m in diameter, including designs for vacuum, EUV vacuum, water, blood and autoclave sterilization.
Integrated robot joint combining a zero-backlash high-ratio gear, frameless torque motor and absolute encoder. Offered in 75, 86 and 97 mm OD sizes for traditional and collaborative robots.
Design of motors and mechatronic systems to application requirements, using finite element magnetic, mechanical and thermal simulation, CFD cooling analysis, and functional testing.
Prototype and low-volume production of specialty coils, magnet assemblies, mechatronic assemblies and actuators; designs transfer to high-volume production through parent company Allient.
