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 speed range, low heat and maintenance-free procedure. Stepper Motors provide high torque and smooth low speed operation.
Speed is typically managed by manual procedure on the driver or by an external change, or with an external 0~10 VDC. Swiftness control systems typically make use of gearheads to increase output torque. Gear types range from spur, worm or helical / hypoid depending on torque needs and budgets.
Mounting configurations vary to depending on space constraints or style of the application.
The drives are high performance and durable and show 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 constant application of aluminium die casting technology, which ensures a high degree of rigidity for the apparatus and motor housing concurrently.
Each drive is produced and tested particularly for each order and customer. A advanced modular system permits an excellent diversity of types and a optimum degree of customization to client requirements.
In both rotation directions, defined end positions are guarded by two position limit switches. This uncomplicated remedy 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 irrigation gearbox forwards and backwards.
A gearmotor delivers high torque at low horsepower or low rate. The speed specifications for these motors are regular speed and stall-speed torque. These motors make use of gears, typically assembled as a gearbox, to lessen speed, which makes more torque available. Gearmotors ‘re normally used in applications that need a whole 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 utilized as gearmotors … a lot of which are found in automotive applications.
Gearmotors have several 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, thus reducing engineering costs.
Another benefit of gearmotors is that having the right combination of engine and gearing may prolong design life and allow for optimum power management and use.
Such problems are common when a separate engine 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 utilization of new specialty components, coatings and bearings, and in addition improved gear tooth designs that are optimized for noise reduction, increase in power and improved life, all of which allows for improved performance in smaller packages. More after the jump.
Conceptually, motors and gearboxes could be combined and matched as had a need to best fit the application form, but in the finish, the complete gearmotor is the driving factor. There are a variety of motors and gearbox types which can be combined; for example, a right position wormgear, planetary and parallel shaft gearbox could be combined with permanent magnet dc, ac induction, or brushless dc motors.
