For applications where adjustable speeds are essential, typically an AC motor with an Inverter or brush motors are used. Brushless DC motors are an advanced option because of their wide swiftness range, low high temperature and maintenance-free procedure. Stepper Motors offer high torque and easy low speed operation.
Speed is typically managed by manual procedure on the driver or by an exterior change, or with an external 0~10 VDC. Velocity control systems typically utilize gearheads to increase result torque. Gear types range between spur, worm or helical / hypoid based on torque needs and budgets.
Mounting configurations differ to depending on space constraints or design of the application.
The drives are irrigation gearbox powerful and durable and show a compact 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 accomplished through the consistent application of light weight aluminum die casting technology, which guarantees 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 amount of customization to client requirements.
In both rotation directions, defined end positions are guarded by two position limit switches. This uncomplicated alternative does not only simplify the cabling, but also makes it possible to configure the finish positions quickly and easily. 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 acceleration. The speed specs for these motors are normal speed and stall-swiftness torque. These motors make use of gears, typically assembled as a gearbox, to reduce speed, making more torque available. Gearmotors are most often used in applications that need 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 used as gearmotors … a lot of which are used in automotive applications.
Gearmotors have several advantages over other styles of motor/equipment combinations. Perhaps most of all, can simplify style and implementation by eliminating the stage of separately developing and integrating the motors with the gears, thus reducing engineering costs.
Another benefit of gearmotors is definitely 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 electric motor and gear reducer are linked 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.
Improvements in gearmotor technology include the use of new specialty components, coatings and bearings, and also improved gear tooth designs that are optimized for sound reduction, increase in strength and improved life, which allows for improved overall performance in smaller packages. More following the jump.
Conceptually, motors and gearboxes could be blended and matched as had a need to greatest fit the application form, but in the end, the complete gearmotor may be the driving factor. There are a number of motors and gearbox types that can be combined; for example, a right position wormgear, planetary and parallel shaft gearbox could be combined with permanent magnet dc, ac induction, or brushless dc motors.
