Before we dive into the different types of gearmotors, let's start with a brief overview of what gearmotors are and how they work. Gearmotors are an essential component in many industrial applications.
The motion is stable, the ability to resist shock and vibration is strong because several planetary wheels with the same structure are used and distributed evenly around the central wheel, which can balance the forces of the planetary wheel and the rotating arm.
The first port of call when choosing a motor is to understand what torque and speed you require. On top of this you need to think about basic functional parameters such as the physical size of the motor – whether it be the motor frame/body or the shaft size or the mounting holes.
For industrial squirrel cage induction motors are used mostly for the motor and drive systems applications. Synchronous motors are very rarely used below 40kW output because of the higher cost compared to induction motors.
Three-phase motors (also annotated numerically as 3-phase motors) are widely used in industry and have become the workhorse of many mechanical and electromechanical systems because of their relative simplicity, proven reliability, and long service life.
AC motors are viable power sources for a range of applications due to their flexibility, efficiency and quiet operation. General uses for AC motors include pumps, water heaters, lawn and garden equipment, ovens, and off-road motorized equipment.
Simply put, a gear motor is an electric motor coupled with a gearbox. In most cases, the addition of a gearbox is intended to limit the speed of the motor’s shaft and increase the motor’s output torque.
