For applications where variable speeds are necessary, typically an AC electric motor with an Inverter or brush motors are used. Brushless DC motors are an advanced option due to their wide rate range, low warmth and maintenance-free operation. Stepper Motors offer high torque and simple low speed operation.
Speed is typically controlled by manual procedure on the driver or by an exterior switch, or with an external 0~10 VDC. Swiftness control systems typically utilize gearheads to increase output torque. Gear types range between spur, worm or helical / hypoid based on torque demands and budgets.
Mounting configurations differ to depending 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 combination of a spur/worm gear drive with motors optimized for performance. This is achieved through the consistent application of light weight aluminum die casting technology, which guarantees a high degree of rigidity for the gear and motor housing at the same time.
Each drive is produced and tested particularly for each order and customer. A advanced modular system permits an excellent diversity of types and a optimum amount of customization to irrigation gearbox customer requirements.
In both rotation directions, described end positions are protected 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 precision of the limit switches ensures safe operation shifting forwards and backwards.
A gearmotor delivers high torque at low horsepower or low velocity. The speed specs for these motors are regular speed and stall-swiftness torque. These motors make use of gears, typically assembled as a gearbox, to lessen speed, making more torque available. Gearmotors are most often utilized in applications that need a lot of force to move heavy objects.

By and large, most industrial gearmotors make use of ac motors, typically fixed-speed motors. However, dc motors can also be used as gearmotors … a lot of which are used in automotive applications.
Gearmotors have a number of advantages over other types of motor/equipment combinations. Perhaps most importantly, can simplify design and implementation through the elimination of the stage of separately designing and integrating the motors with the gears, therefore reducing engineering costs.
Another advantage of gearmotors is that getting the right combination of motor and gearing may prolong design life and invite for the best power management and use.

Such problems are common when a separate electric motor and gear reducer are connected together and result in more engineering time and cost as well as the potential for misalignment causing bearing failure and eventually reduced useful life.
Developments in gearmotor technology include the usage of new specialty materials, coatings and bearings, and also improved gear tooth styles that are optimized for sound reduction, increase in strength and improved life, all of which allows for improved functionality in smaller deals. More after the jump.
Conceptually, motors and gearboxes can be mixed and matched as had a need to greatest fit the application form, but in the finish, the complete gearmotor may be the driving factor. There are numerous of motors and gearbox types which can be mixed; for example, a right position wormgear, planetary and parallel shaft gearbox could be combined with long lasting magnet dc, ac induction, or brushless dc motors.
