For applications where adjustable speeds are necessary, typically an AC engine with an Inverter or brush motors are used. Brushless DC motors are a sophisticated option because of their wide speed range, low heat and maintenance-free operation. Stepper Motors offer high torque and soft low speed operation.
Speed is typically managed by manual procedure on the driver or by an external irrigation gearbox switch, or with an external 0~10 VDC. Acceleration control systems typically utilize gearheads to increase output torque. Gear types range from spur, worm or helical / hypoid based on torque demands and budgets.
Mounting configurations vary to depending on space constraints or style of the application.
The drives are high performance 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. This is attained through the consistent application of aluminium die casting technology, which guarantees a high degree of rigidity for the gear and motor housing concurrently.
Each drive is produced and tested specifically for every order and customer. A sophisticated modular system permits an excellent diversity of types and a optimum amount of customization to customer requirements.
In both rotation directions, defined end positions are shielded by two position limit switches. This uncomplicated remedy 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 guarantees safe operation shifting forwards and backwards.
A gearmotor provides high torque at low horsepower or low quickness. The speed specs for these motors are normal speed and stall-acceleration torque. These motors make use of gears, typically assembled as a gearbox, to lessen speed, making more torque available. Gearmotors are most often used in applications that require a lot of force to move heavy objects.

More often than not, most industrial gearmotors use 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 several advantages over other types of motor/gear combinations. Perhaps most importantly, can simplify style and implementation through the elimination of the step of separately designing and integrating the motors with the gears, therefore reducing engineering costs.
Another advantage of gearmotors is certainly that getting the right combination of electric motor and gearing may prolong design life and invite for ideal power management and use.

Such problems are normal when a separate engine and gear reducer are linked together and lead to more engineering time and cost along with the potential for misalignment leading to bearing failure and ultimately reduced useful life.
Improvements in gearmotor technology include the use of new specialty components, coatings and bearings, and in addition improved gear tooth designs that are optimized for noise reduction, increase in power and improved life, which allows for improved overall performance in smaller deals. More following the jump.
Conceptually, motors and gearboxes can be blended and matched as needed to best fit the application, but in the end, the complete gearmotor is the driving factor. There are a number of motors and gearbox types that can be combined; for example, the right angle wormgear, planetary and parallel shaft gearbox can be combined with long term magnet dc, ac induction, or brushless dc motors.
