Miniature Motors

A reliable source for Miniature Motors information and leading Miniature Motors Companies & Manufacturers.

Miniature motors are small electric motors that convert electrical energy into mechanical energy. Miniature motors are used where larger motors cannot fit. A small motor ranges from 1.24 inches in length and 0.511 inches in diameter. At 8,000 rpm, it is capable of 2.5 W of output power. Read More…

Miniature Motors Miniature motors, also referred to as micro motors or small motors, are fractional horsepower motors that must fit the frame size and/or less than one horsepower requirements, as well as fit the size dimensions of a couple inches or less.

miniature vibrating motor

A miniature motor is constructed with Neodymium magnets, priceless metal brushes, and a moving-coil rotor with a Rhombic-wound winding for maximum winding density. Miniature motors have five ratios ranging from 4:1 to 1,118:1, a torque capacity of 0.35 Nm continuous and 0.53 Nm intermittent, and a matching 0.511-inch planetary gearhead. Many micro motors are made with lighter materials to maximize the power-to-weight ratio.

Types of Miniature Motors

Brushed Miniature DC Motor

A brushed DC motor is ideal for both large and small devices. A brushed DC motor produces low friction, low starting voltages, negligible iron losses, great efficiency, good thermal dissipation, and a linear relationship between torque and speed. These tiny motors are primarily made to offer outstanding speed-to-torque performance with minimal joule heating.

Miniature Brushless DC Motor

Miniature BLDC motor technology maintains the slotted and slotless motors' outstanding performance. These motors have excellent position control, superb speed, outstanding torque, and extended life. While slotted DC brushless motors employ stators with windings and lamination, slotless Brushless DC motors use an ironless cylindrical loop created using a similar winding technique.

Miniature Stepper Motor

Any other permanent magnet stepper motor cannot be used with these motors. These motors' cutting-edge technology enables a very fantastic dynamic motor act. The single thin disc magnet creates a shorter magnetic circuit. This means a miniature stepper motor won’t lose as much iron. That allows for higher acceleration compared to traditional steppers. Miniature stepper motors are ideal for applications that require rapid incremental motion.

Applications of Mini Motor

  • Industrial robots: Miniature motors help Industrial robots perform quick, accurate movements. Improved industrial robots are created as motor efficiency and power density increase. Robots become lighter, more nimble, and more energy-efficient, allowing for both improved mobility and quicker productivity. This reduces cost of ownership for automation solutions.
  • Pick and place assembly: Since the 1980s, manufacturers have used pick-and-place (P&P) or surface-mounted technology (SMT) equipment to assemble semiconductors and electronic components. A robot arm picks up a part and accurately attaches or positions it on a circuit board. Miniature motors are a great solution because they are compact enough to fit in the robot and enable rapid, accurate movements. Assembly systems can complete millions of cycles, so the motor needs a long service life.
  • Material handling: Materials must be moved around during industrial operations. This automation solution may include a simple robotic arm or a sophisticated network of machinery wired for material handling tasks like stacking and sorting. The system can transport goods with the least amount of assistance from humans to storage or the producing location. Material handling automation guarantees minimal waste and effective utilization of inventories. Since they take up less room and contribute to energy conservation, miniature motors can frequently take the place of other motor types in these solutions. They help complete tasks that require precise and delicate handling.
  • Yarn winding machinery: In the textile industry, yarn winding machines are frequently used to wind yarn for processes like knitting or weaving. To avoid tangling (which halts production and damages material), yarn winders must accurately position and guide the yarn. Small motors can supply the accurate motions needed.
  • Conveyor system: Conveyor systems rapidly transfer components or materials. Conveyors are essential to the production process in many industries. High-performance micro motors allow Conveyor systems to transport heavy loads using a smaller space. The reduced motor size opens up more design possibilities.
  • Modern tiny motors can now handle various demanding requirements of industrial automation applications. Engineers may be confident that as motor technology improves, it will be able to deliver the power required for practically all applications that depend on precise miniature motions.
