For applications where variable speeds are necessary, typically an AC electric motor with an Inverter or brush motors are used. Brushless DC motors are a sophisticated option due to their wide acceleration range, low high temperature and maintenance-free operation. Stepper Motors provide high torque and smooth low speed operation.
Speed is typically managed by manual irrigation gearbox procedure on the driver or by an external switch, or with an external 0~10 VDC. Speed control systems typically use gearheads to increase output torque. Gear types range between spur, worm or helical / hypoid depending 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 design is manufactured possible through the mixture of a spur/worm gear drive with motors optimized for performance. This is achieved through the constant application of light weight aluminum die casting technology, which guarantees a high amount of rigidity for the apparatus and motor housing at the same time.
Each drive is produced and tested particularly for each order and customer. A sophisticated modular system allows for a great diversity of types and a optimum degree of customization to customer requirements.
In both rotation directions, defined end positions are secured by two position limit switches. This uncomplicated solution does not only simplify the cabling, but also makes it possible to configure the end positions efficiently. 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 swiftness. The speed specifications for these motors are normal speed and stall-swiftness torque. These motors use gears, typically assembled as a gearbox, to reduce speed, making more torque offered. Gearmotors are most often utilized in applications that need a lot of force to go heavy objects.
By and large, most industrial gearmotors use ac motors, typically fixed-speed motors. Nevertheless, dc motors can also be used as gearmotors … a lot of which are found in automotive applications.
Gearmotors have numerous advantages over other types of motor/equipment combinations. Perhaps most of all, can simplify design and implementation through the elimination of the step of separately developing and integrating the motors with the gears, therefore reducing engineering costs.
Another advantage of gearmotors is certainly that having the right combination of engine and gearing can prolong design life and invite for optimum power management and use.
Such problems are normal when a separate motor and gear reducer are connected together and result in more engineering time and cost as well as the potential for misalignment leading to bearing failure and eventually reduced useful life.
Developments in gearmotor technology include the utilization of new specialty components, coatings and bearings, and in addition improved gear tooth designs that are optimized for noise reduction, increase in strength 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 form, but in the end, the complete gearmotor is the driving factor. There are a number of motors and gearbox types which can be combined; for example, the right position wormgear, planetary and parallel shaft gearbox can be combined with long term magnet dc, ac induction, or brushless dc motors.
