For applications where variable speeds are necessary, typically an AC engine with an Inverter or brush motors are used. Brushless DC motors are a irrigation gearbox sophisticated option because of their wide speed range, low warmth and maintenance-free operation. Stepper Motors provide high torque and smooth low speed operation.
Speed is typically controlled by manual procedure on the driver or by an external switch, or with an exterior 0~10 VDC. Rate control systems typically use gearheads to increase result torque. Gear types range between spur, worm or helical / hypoid based on torque demands and budgets.
Mounting configurations vary to depending on space constraints or design of the application.
The drives are high performance and durable and feature a concise and lightweight design.
The compact design is manufactured possible through the mixture of a spur/worm gear drive with motors optimized for performance. That is achieved through the consistent application of aluminum die casting technology, 
which ensures a high amount of rigidity for the apparatus and motor housing at the same time.
Each drive is produced and tested particularly for every order and customer. A advanced modular system allows for a great diversity of types and a optimum degree of customization to customer requirements.
In both rotation directions, described end positions are protected by two position limit switches. This uncomplicated solution does not just simplify the cabling, but also makes it possible to configure the finish positions quickly and easily. 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 acceleration. The speed specs for these motors are regular speed and stall-velocity torque. These motors make use of gears, typically assembled as a gearbox, to reduce speed, which makes more torque offered. Gearmotors are most often utilized in applications that require a lot of force to go heavy objects.
By and large, most industrial gearmotors use ac motors, typically fixed-speed motors. Nevertheless, dc motors may also be utilized as gearmotors … a lot of which are used in automotive applications.
Gearmotors have a number of advantages over other types of motor/gear combinations. Perhaps most of all, can simplify style and implementation through the elimination of the step of separately creating and integrating the motors with the gears, hence reducing engineering costs.
Another benefit of gearmotors is that having the right combination of electric motor and gearing can prolong design life and allow for the best possible power management and use.
Such problems are common when a separate motor and gear reducer are connected together and lead to more engineering time and cost as well as the potential for misalignment leading to bearing failure and eventually reduced useful life.
Advances in gearmotor technology include the utilization of new specialty components, coatings and bearings, and also improved gear tooth styles that are optimized for noise reduction, increase in power and improved life, which allows for improved overall performance in smaller deals. More after the jump.
Conceptually, motors and gearboxes can be combined and matched as needed to best fit the application, but in the end, the complete gearmotor is the driving factor. There are a variety of motors and gearbox types which can be mixed; for example, a right angle wormgear, planetary and parallel shaft gearbox can be combined with long term magnet dc, ac induction, or brushless dc motors.
