For applications where adjustable speeds are essential, typically an AC electric motor 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 provide high torque and even low speed operation.
Speed is typically controlled by manual operation on the driver or by an exterior change, or with an exterior 0~10 VDC. Swiftness control systems typically utilize gearheads to increase output torque. Gear types range from spur, worm or helical / hypoid based on torque needs and budgets.
Mounting configurations differ to based on space constraints or style of the application.
The drives are high performance and durable and feature a concise and lightweight design.
The compact irrigation gearbox design is manufactured possible through the combination of a spur/worm gear drive with motors optimized for performance. This is attained through the constant application of aluminium die casting technology, which guarantees a high amount of rigidity for the gear and motor housing simultaneously.
Each drive is produced and tested particularly for every order and customer. A sophisticated modular system permits an excellent diversity of types and a maximum amount of customization to consumer requirements.
In both rotation directions, described end positions are safeguarded by two position limit switches. This uncomplicated answer does not only simplify the cabling, but also can help you configure the end positions quickly and easily. The high shut-off precision of the limit switches guarantees safe operation shifting forwards and backwards.
A gearmotor delivers high torque at low horsepower or low acceleration. The speed specs for these motors are regular speed and stall-acceleration torque. These motors use gears, typically assembled as a gearbox, to lessen speed, making more torque available. Gearmotors ‘re normally used in applications that need a lot of force to move heavy objects.
More often than not, 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 numerous advantages over other types of motor/gear combinations. Perhaps most importantly, can simplify design and implementation by eliminating the step of separately creating and integrating the motors with the gears, hence reducing engineering costs.
Another benefit of gearmotors can be that getting the right combination of electric motor and gearing can prolong design life and allow for ideal 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 ultimately reduced useful life.
Advances in gearmotor technology include the usage of new specialty components, coatings and bearings, and in addition improved gear tooth designs that are optimized for sound reduction, increase in power and improved life, all of which allows for improved functionality in smaller packages. More following the jump.
Conceptually, motors and gearboxes could be combined and matched as needed to best fit the application form, but in the end, the complete gearmotor is the driving factor. There are numerous of motors and gearbox types that can be mixed; for example, the right position wormgear, planetary and parallel shaft gearbox could be combined with long lasting magnet dc, ac induction, or brushless dc motors.
