For applications where variable speeds are essential, typically an AC motor with an Inverter or brush motors are used. Brushless DC motors are an advanced option due to their wide swiftness range, low heat and maintenance-free operation. Stepper Motors offer high torque and simple low speed operation.
Speed is typically controlled by manual procedure on the driver or by an exterior switch, or with an exterior 0~10 VDC. Velocity control systems typically make use of gearheads to increase output torque. Gear types range between spur, worm or helical / hypoid depending on torque demands and budgets.
Mounting configurations vary to based on space constraints or design of the application.
The drives are powerful 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. That is achieved through the consistent application of light weight aluminum die casting technology, which ensures 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 client requirements.
In both rotation directions, described end positions are safeguarded by two position limit switches. This uncomplicated remedy does not just simplify the cabling, but also makes it possible to configure the end positions quickly and easily. The high shut-off precision of the limit switches irrigation gearbox guarantees safe operation moving 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-quickness torque. These motors use gears, typically assembled as a gearbox, to reduce speed, making more torque obtainable. Gearmotors are most often utilized in applications that need a whole lot of force to go heavy objects.
More often than not, most industrial gearmotors use ac motors, typically fixed-speed motors. However, dc motors may also be used as gearmotors … a whole lot of which are used in automotive applications.
Gearmotors have numerous advantages over other types of motor/equipment combinations. Perhaps most of all, can simplify style and implementation through the elimination of the stage of separately developing and integrating the motors with the gears, hence reducing engineering costs.
Another benefit of gearmotors is usually that having the right combination of engine 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 as well as the potential for misalignment leading to bearing failure and ultimately reduced useful life.
Improvements in gearmotor technology include the utilization of new specialty materials, coatings and bearings, and also improved gear tooth designs that are optimized for noise reduction, increase in strength and improved life, which allows for improved performance in smaller packages. More following the jump.
Conceptually, motors and gearboxes can be combined and matched as needed to greatest fit the application, but in the finish, the complete gearmotor may be the driving factor. There are a variety of motors and gearbox types that can be mixed; for example, a right angle wormgear, planetary and parallel shaft gearbox could be combined with long lasting magnet dc, ac induction, or brushless dc motors.
