In a recent video on new ElectroCraft motors, my colleague Paul Heney and I got to review integrated offerings that let designers get higher torque even while maintaining efficiency. The LRPX units are sold as gear motors — not as motor with added gearboxes. This means motor performance is optimized for gear input limitations. An eight-pole […]
Bodine’s new planetary PMDC gearmotors double torque
Bodine Electric Co. now sells 24A4-60P planetary PMDC gearmotors. These integral gearmotors combine Bodine’s high-performance type 24A PMDC motor with the all-new 60P (60 mm) planetary gearhead. It is suitable for applications that need higher torque than conventional helical or spur gearheads of a similar size can provide … and where very low backlash gearhead […]
How to design quiet gearmotors: Gear engagement, housing geometry, and more
What applications need quiet gearmotors? The answer might surprise you — because the human ear can detect noise at 10 dB lower than ambient levels, and many gearmotors operate in close proximity to people. In this technical article, we outline recent staff engineers’ research and development into the problem (and potential solutions for) gearmotor noise. […]
Brother Gearmotors to showcase new right-angle hypoid gearing brushless dc gearmotors at Process Expo
Brother Gearmotors, a division of Brother International Corporation, will showcase its new line of brushless dc electric gearmotors (BLDC) at Process Expo, September 19-22 in Chicago. Brother Gearmotors will be located at Booth #4302. Also known as electronically commutated motors, Brother’s portfolio of brushless dc gearmotors are suitable for environments requiring virtually maintenance-free operation and […]
New right-angle hypoid gear brushless dc gearmotors from Brother Gearmotors
Brother Gearmotors’ new line of brushless dc electric gearmotors (BLDC), also known as electronically commutated motors, expands the company’s portfolio of brushless dc gearmotors that are ideal for environments requiring virtually maintenance-free operation and accurate speed control as well as operation over a wide speed range. They are also desirable for settings where brush dust […]
What are design considerations for integral horsepower gearmotors?
An integral horsepower gearmotor is any motor with a horsepower of 1 and above, as opposed to fractional horsepower motors that are less than 1 hp. The design considerations for integral horsepower motors are going to be fairly similar to fractional horsepower motors because the same types of parameters are important. So for instance, torque […]
How to get zero backlash out of gearing?
Gearmotors use gears to reduce speed, which makes more torque available. The kind of gears used in gearmotors have an impact on the available torque, but also on things like noise levels and accuracy. In fact, one of the more common sources of inaccuracy in gearmotors is due to gear backlash. So reducing the amount […]
What are gearmotors used for speed-control applications?
Aside from their use in position control applications, gearmotors are used in speed-control applications as well. The reality is that many different types of gearmotors can be used for speed control. As with any design problem, the requirements of the unique application will dictate what type of motor is best suited for the job. A […]
What are gearmotors used for position-control applications?
Gearmotors are often used in position control applications. A prime example would be in packaging or material handling where a load needs to be picked up or placed at a specified location, or applications with more precise requirements such as micro-positioning in high-precision manufacturing or dispensing. Application requirements will dictate the level of accuracy needed […]
Dodge Quantis gear reducers and gearmotors now in higher ratios
The Baldor Dodge Quantis product family — a full line of modular gearmotors and gear drives — has expanded to offer four and five stages of gear reduction for all three types of gear arrangements; in-line helical (ILH), offset parallel (MSM) and right angle helical bevel (RHB). Quantis reducers and gearmotors can now be configured in ratios over 7,500:1 […]
