For applications where variable speeds are necessary, typically an AC motor with an Inverter or brush motors are used. Brushless DC motors are an advanced option due to their wide acceleration range, low warmth and maintenance-free procedure. Stepper Motors provide high torque and soft low speed operation.
Speed is typically managed by manual operation on the driver or by an external change, or with an exterior 0~10 VDC. Swiftness control systems typically utilize gearheads to increase output torque. Gear types range between spur, worm or helical / hypoid based on torque demands and budgets.
Mounting configurations vary to based on space constraints or style of the application.
The drives are powerful and durable and feature a compact and lightweight design.
The compact design is made possible through the combination of a spur/worm gear drive with motors optimized for performance. This is achieved through the consistent application of aluminium die casting technology, which ensures a high degree of rigidity for the gear and motor housing concurrently.
Each drive is produced and tested specifically for each order and customer. A sophisticated modular system permits a great diversity of types and a optimum amount of customization to client requirements.
In both rotation directions, defined end positions are safeguarded by two position limit switches. This uncomplicated answer does not only simplify the cabling, but also makes it possible to configure the finish positions quickly and easily. The high shut-off accuracy of the limit switches guarantees safe operation moving forwards and backwards.
A gearmotor provides high torque at low horsepower or low swiftness. The speed specifications for these motors are regular speed and stall-quickness torque. These motors make use of gears, typically assembled as a gearbox, to reduce speed, which makes more torque obtainable. Gearmotors are most often used in applications that need a whole lot of force to move heavy objects.
More often than not, most industrial gearmotors use ac motors, typically fixed-speed motors. However, dc motors may also be utilized as gearmotors … a whole lot of which are used in automotive applications.
Gearmotors have a number of advantages over other styles of motor/equipment combinations. Perhaps most importantly, can simplify style and implementation through the elimination of the step of separately creating and integrating the motors with the gears, therefore reducing engineering costs.
Another advantage 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 normal when a separate engine and gear reducer are linked together and result in more engineering time and cost as well as the potential for irrigation gearbox 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 styles that are optimized for sound reduction, increase in power and improved life, which allows for improved overall performance in smaller packages. More following the jump.
Conceptually, motors and gearboxes can be mixed and matched as had a need to best fit the application form, but in the end, 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 permanent magnet dc, ac induction, or brushless dc motors.
