maxon motors - Right Angle Spiroid® Gear

Designed to achieve maximum torque with minimal space

maxon precision motors introduces right angle gearheads designed to be configured with maxon's 22mm and 32mm dc motors. These compact, lightweight and high torque gearheads were developed to transmit power at 90deg in the smallest possible form factor. The Spiroid® technology incorporated in the gearhead design offers a number of performance benefits:


Extremely high torque transmission
High stiffness / Low deflection with large applied loads
Back-drivable (4:1 ratio) & Non-back drivable (31:1 ratio) versions
Compact size
Low backlash
Up to 3:1 "gear teeth" contact ratio
Quiet operation
High Torque to Space Ratio (HTSR) technology

The 22mm and 32mm right angle gearheads are available in either a 4:1 or 31:1 ratio, which may be mounted directly onto many of maxon's brushed/brushless motors OR configured with different ratios of maxon's GP22 and GP32 planetary gearheads. This results in a wide range of achievable gear reductions. The motor and gearhead combinations are ideally suited for a variety of applications particularly where an output shaft perpendicular to the motor axis is desired.

maxon precision motors, inc. manufactures small, high quality, DC brushless motors used in such industries as medical, semiconductor, test and measurement, robotics and manufacturing, among others. These motors range in size from 4mm - 90 mm and are available up to 500 watts. maxon's rhombic wound ironless rotor motors provide exceptionally high efficiency, low EMI emissions, fast acceleration, no preferred rotor position, linear speed and torque constants (accurate control) and long life. maxon also offers gearheads, encoders and tachometers to compliment its motors as well as a complete family of control electronics for velocity, torque and position control.

PQ12-R Micro Linear Servo

PQ12-R Micro Linear Servo

The PQ12-R series of linear servos are the smallest affordable linear servo on the market today. Small enough to fit inside a tic tac box, it's very powerful with a maximum force of over 11lbs. It operates as a direct plug-and-play replacement for standard rotary servos, using the same standard 3 wire connector. Regardless of how you drive your servos, be it with an RC receiver, an Arduino board, or a VEX micro-controller, the PQ12-R servo will function in place of a regular servo, but with the added benefit of providing linear motion. They're available in a 20mm stroke coupled with gear ratio options of 30:1, 63:1 and 100:1 cover a large variety of applications. Our PQ12 is popular used in a variety of robotics applications, medical devices, radio control and 3D printable bionic hands. Our PQ12 is proudly designed in Canada by our in-house team of engineers and thoroughly tested before leaving our facility.
