High Torque Low RPM Motors
High torque low RPM motors describe motors that provide a lot of power and can control motion at lower speeds. These motors are specifically designed to move large, heavy objects in a smooth, slow, and controlled manner. The high torque makes it possible to alter the position of doors, gates, lifts, platforms, and other objects of considerable weight. These devices are integrated into many automated or electronically controlled systems. Lower RPMs help to ensure that this is completed safely and smoothly so there is no danger to people or objects in the surrounding area or to the equipment itself.
Low RPM motors are designed to generate higher torque levels at a lower speed by their very design. They therefore do not require a gearbox to modify the output. High-speed motors typically require this addition to make the motor’s speed adjustable, but this feature can be bypassed in a low-speed motor.
Low-speed electric motors are most frequently used for automated systems that respond to a sensor or electrical control. Automated safety barriers, security gates, and garage doors are common examples of low-speed high torque motor applications. Low-speed electric motors are also used in many critical automated systems on aircraft, spacecraft, and other settings. The controlled operation of these motors is conducive to maintaining safety where it is imperative.
High torque low-speed motors are also integral to the careful guidance and movement of heavy machinery used to move cargo and heavy loads. These motors are incorporated into lifts, freight systems, and other equipment. The low speed of these motors and their heavy lifting capability works well for devices that must operate along a track or fixed path, even when the load in motion is especially large and/or heavy.
How Is Torque Created In A Motor?
Torque is created as energy is introduced into a motor. The current creates an interaction between the magnetic fields of the stator windings and the rotor, which causes the rotor to spin, converting the electrical energy into mechanical power .
What Are The Advantages Of High Torque And Low Speed In A Motor?
The primary advantages of high torque low RPM motors is their ability to move heavy and large loads at a slow, controlled rate. By their design, these motors provide a lot of power and operate at a low speed without the addition of a gearbox or another form of speed control. As they run at lower speeds and can move heavy loads in a smooth, predictable manner, they are an asset to the safety of automated systems in many critical settings, including aboard aircraft, in public places, and loading docks.
Why Does Torque Drop At High RPM?
In electric motors, mechanical efficiency declines as speed or RPMs increase. This is a result of frictional resistance, which hinders the output of torque.
Why Do DC Motors Have More Torque?
DC motors can be considered high torque motors as this type of motor draws a large amount of current at starting and that field current is high. This amounts to increased stator flux that serves to produce a high starting torque.
How Do You Increase The Torque Of A Motor?
The torque of an electric motor can be increased by increasing the armature current through an increase in supply voltage. This can be accomplished with the incorporation of a speed controller or the addition of gears and other modifications.
