For applications where adjustable speeds are necessary, typically an AC engine with an Inverter or brush motors are used. Brushless DC motors are an advanced option due to their wide quickness range, low warmth and maintenance-free operation. Stepper Motors provide high torque and clean 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 use gearheads to increase result torque. Gear types range between spur, worm or helical / hypoid depending on torque needs and budgets.
Mounting configurations vary to based on space constraints or design of the application.
The drives are powerful and durable and show a compact and lightweight design.
The compact design is manufactured possible through the combination of a spur/worm gear drive with motors optimized for performance. This is accomplished through the consistent application of aluminium die casting technology, which guarantees a high degree of rigidity for the gear and motor housing at the same time.
Each drive is produced and tested specifically for every order and customer. A sophisticated modular system allows for a great diversity of types and a maximum amount of customization to customer requirements.
In both rotation directions, described end positions are safeguarded by two position limit switches. This uncomplicated remedy 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 ensures safe operation moving forwards and backwards.
A gearmotor irrigation gearbox delivers high torque at low horsepower or low velocity. 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, which makes more torque obtainable. Gearmotors are most often used in applications that require a lot of force to move heavy objects.
More often than not, most industrial gearmotors make use of ac motors, typically fixed-speed motors. Nevertheless, dc motors may also be used as gearmotors … a whole lot of which are found in automotive applications.
Gearmotors have several advantages over other styles of motor/gear combinations. Perhaps most importantly, can simplify style and implementation through the elimination of the step of separately developing and integrating the motors with the gears, hence reducing engineering costs.
Another benefit of gearmotors is certainly that getting the right combination of engine and gearing can prolong design life and allow for the best power management and use.
Such problems are common when a separate electric motor and gear reducer are linked together and lead to more engineering time and cost and also the potential for misalignment causing bearing failure and ultimately reduced useful life.
Improvements in gearmotor technology include the use 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 performance in smaller deals. More following the jump.
Conceptually, motors and gearboxes could be combined and matched as had a need to best fit the application, but in the finish, the complete gearmotor is the driving factor. There are many of motors and gearbox types which can be mixed; for example, a right position wormgear, planetary and parallel shaft gearbox could be combined with long lasting magnet dc, ac induction, or brushless dc motors.
