For applications where variable speeds are necessary, typically an AC engine with an Inverter or brush motors are used. Brushless DC motors are a sophisticated option due to their wide rate range, low temperature and maintenance-free procedure. Stepper Motors offer high torque and easy low speed operation.
Speed is typically managed by manual operation on the driver or by an external switch, or with an exterior 0~10 VDC. Rate control systems typically make use of gearheads to irrigation gearbox increase result torque. Gear types range between spur, worm or helical / hypoid depending on torque needs 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. That is attained through the consistent application of light weight aluminum die casting technology, which guarantees a high amount of rigidity for the gear and motor housing concurrently.
Each drive is produced and tested particularly for every order and customer. A sophisticated modular system allows for an excellent diversity of types and a optimum degree of customization to consumer requirements.
In both rotation directions, described end positions are protected by two position limit switches. This uncomplicated solution does not only simplify the cabling, but also can help you configure the finish positions quickly and easily. The high shut-off accuracy of the limit switches guarantees safe operation shifting forwards and backwards.
A gearmotor delivers high torque at low horsepower or low quickness. The speed specifications for these motors are regular speed and stall-quickness torque. These motors use gears, typically assembled as a gearbox, to reduce speed, which makes more torque offered. Gearmotors ‘re normally utilized in applications that require a whole lot of force to go heavy objects.
More often than not, most industrial gearmotors make use of ac motors, typically fixed-speed motors. Nevertheless, 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/equipment combinations. Perhaps most of all, can simplify design and implementation through the elimination of the stage of separately creating and integrating the motors with the gears, therefore reducing engineering costs.
Another advantage of gearmotors is that having the right combination of electric motor and gearing may prolong design life and allow for the best possible power management and use.
Such problems are common when a separate engine and gear reducer are connected together and lead to more engineering time and cost along with the potential for misalignment leading to bearing failure and ultimately reduced useful life.
Developments in gearmotor technology include the use of new specialty components, coatings and bearings, and also improved gear tooth designs that are optimized for noise reduction, increase in power and improved life, which allows for improved performance in smaller packages. More after the jump.
Conceptually, motors and gearboxes could be mixed and matched as needed to greatest fit the application, but in the end, the complete gearmotor may be the driving factor. There are a variety of motors and gearbox types which 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.
