high efficiency of Wuma planetary gearbox

Wuma planetary gearbox designed for servo applications requiring precision, durability, and long trouble free operation. The reducer motor are high efficiency gearheads that maximize the power transmission capability. They are designed with low backlash to reduce shock loads in dynamic reversing applications. They mount directly to the BSM servo motor family to provide torque multiplication, speed reduction, and inertia matching.

the application in almost any field of automation

Wuma RV Worm Gear Reducer Offering excellent performance, the offers various options when building your machines while enables the use of space-saving right angle servo gearboxes for many applications for which earlier coaxial gearboxes were necessary.
low backlash high precision reducer motor has been designed for direct mounting onto servomotors. The available wide range of sizes and the use of a modular system allows the application in almost any field of automation.

Wuma combination worm gearbox are available in a range of sizes to fit most standard stepper and servo motors, with output variations to match your existing mechanical interfaces. today for a solution that works.
High quality precision combination gearbox for servo applications offering the following benefits: High input speeds Low moment of inertia High torsional rigidity Reduced backlash option High efficiency Can be mounted in any attitude Maintenance-free (applies to most applications).

the actual frequency of the mechanical variable speed gearbox

mechanical variable speed gearbox of the IGBTs in a PWM drive can range from 2 KHz to 15 KHz. Today's newer PWM designs use power IGBTs, which operate at these higher frequencies. By having more pulses in every half cycle, the motor whine associated with gearbox transmission is reduced because the motor windings are now oscillating at a frequency beyond the spectrum of human hearing. how each transition of the alternating voltage output is actually a series of short pulses of varying widths. By varying the width of the pulses in each half cycle, the average power produced has a sine-like output. The number of transitions from positive to negative per second determines the actual frequency to the motor.

designs advantages of the RV Worm Gear Reducer

RV Worm Gear Reducer control the speed of an AC induction motor by varying the motor's supplied voltage and frequency of power, The speed reducers all do not use the same designs in doing so. an AC line supply voltage is brought into the input section. From here, the AC voltage passes into a converter section that uses a diode bridge converter and large DC capacitors to create and maintain a stable, fixed DC bus voltage. The DC voltage passes into the inverter section usually furnished with insulated gate bipolar transistors (IGBTs), which regulate both voltage and frequency to the motor to produce a near sine wave like output.

combination worm gearbox has the most commonly used drive

combination worm gearbox has become the most commonly used drive controller because worm gear reducer works well with motors ranging in size from about 1/2 hp to 500 hp. A significant reason for its popularity is that it's highly reliable, affordable and reflects the least amount of harmonics back into its power source. Most units are rated either 230V or 460V, 3-phase, and provide output frequencies from about 2 Hz to 400 Hz. Nearly 100 manufacturers market the PWM controller.
