For applications where adjustable speeds are necessary, typically an AC motor with an Inverter or brush motors are used. Brushless DC motors are an advanced option due to their wide acceleration range, low high temperature and maintenance-free operation. Stepper Motors offer high torque and easy low speed operation.
Speed is typically managed by manual procedure on the driver or by an external switch, or with an exterior 0~10 VDC. irrigation gearbox quickness control systems typically use gearheads to increase result torque. Gear types range from spur, worm or helical / hypoid based on torque needs and budgets.
Mounting configurations differ to based on space constraints or style of the application.
The drives are powerful and durable and show a concise and lightweight design.
The compact design is made possible through the mixture of a spur/worm gear drive with motors optimized for performance. That is achieved through the constant application of light weight aluminum die casting technology, which ensures a high degree of rigidity for the apparatus and motor housing concurrently.
Each drive is produced and tested specifically for every order and customer. A advanced modular system allows for an excellent diversity of types and a optimum degree of customization to customer requirements.
In both rotation directions, described end positions are secured by two position limit switches. This uncomplicated option does not just simplify the cabling, but also makes it possible to configure the end positions efficiently. The high shut-off accuracy of the limit switches ensures safe operation moving forwards and backwards.
A gearmotor provides high torque at low horsepower or low quickness. The speed specifications for these motors are regular speed and stall-quickness torque. These motors make use of gears, typically assembled as a gearbox, to reduce speed, which makes more torque obtainable. Gearmotors are most often used in applications that need a lot of force to go heavy objects.
More often than not, most industrial gearmotors make use of ac motors, typically fixed-speed motors. However, dc motors can also be utilized as gearmotors … a lot of 
which are used in automotive applications.
Gearmotors have numerous advantages over other types of motor/equipment combinations. Perhaps most importantly, can simplify design and implementation by eliminating the step of separately creating and integrating the motors with the gears, hence reducing engineering costs.
Another advantage of gearmotors is definitely that getting the right combination of electric motor and gearing can prolong design life and allow for ideal power management and use.
Such problems are common when a separate motor and gear reducer are linked together and result in more engineering time and cost as well as the potential for misalignment causing bearing failure and eventually reduced useful life.
Improvements in gearmotor technology include the use of new specialty materials, coatings and bearings, and in addition improved gear tooth designs that are optimized for sound reduction, increase in strength and improved life, all of which allows for improved functionality in smaller packages. More after the jump.
Conceptually, motors and gearboxes can be combined and matched as needed to best fit the application, but in the finish, the complete gearmotor is the driving factor. There are many of motors and gearbox types that can be mixed; for example, the right position wormgear, planetary and parallel shaft gearbox can be combined with permanent magnet dc, ac induction, or brushless dc motors.
