Published: September 17, 2026 The specified backlash of a planetary gearbox might be 15 arcmin, 5 arcmin, or even 1 arcmin. A smaller number generally implies higher reverse positioning capabilities, but without specifying the measurement position, input locking method, and…
Published: September 11, 2026 A common custom gearbox request sounds simple: “Can you change this planetary gearbox from 20:1 to 21:1?” The difference in output speed appears small. With a motor operating at 6,000 rpm: From a gear-design and manufacturing…
Published: SEPTEMBER 7, 2026 The true purpose of a DC motor performance curve is not to show an engineer the motor’s maximum speed or maximum torque in isolation, but to help evaluate whether a specific operating point meets the requirements…
When reviewing a DC motor or DC gear motor datasheet, engineers often encounter two values that differ significantly: Rated Torque and Stall Torque. If a motor has a rated torque of only 2 N·m but a stall torque of 5…
When designing compact automation equipment, medical instruments, robot joints, or smart logistics modules, the choice of the drive unit often determines the overall performance ceiling of the machine. With their small size, convenient control, and high output torque, DC gear…
A Linear Resonant Actuator (LRA) is a compact, efficient, and fast-responding vibration motor used for haptic feedback. Its internal coil is driven by AC power to generate single-axis (X, Y, or Z-axis) reciprocating vibration through a permanent magnet and spring…
Phone vibration looks like a trivial feature. It reminds users of calls, messages and typing inputs. Few people notice the tiny vibration motor inside the device. Engineers have upgraded phone vibration motors step by step. ERM motors dominated early phones…
A lead screw with stepper motor should not be selected only by motor size, rated current, or holding torque. In a real machine, several points must be confirmed. Can the actuator provide enough thrust at the target speed? Can it…
A lead screw stepper motor converts rotary motion into linear motion through a lead screw and nut mechanism, enabling precise positioning of a load. With a compact structure, simple control, and good repeatability, it is widely used in medical devices,…
When using 3D printers, engraving machines, small automation equipment, or robot models, many users face the same problem. The stepper motor may make a sharp squealing sound, buzzing sound, or creaking noise when it is powered on and locked, or…
