What Is a Speed Variator?

A Speed Variator is a device that controls the speed of a machine by using an electromagnet and an electric switch. The electromagnet is composed of two coils and acts differentially on a movable member. A speed variator is often used with an electric motor. To determine the desired speed, a machine can use an electric motor or a speed variator.

Variable multiplier

Variable multipliers are used to improve the speed of multiplication algorithms. This is done by examining two bits of data in each cycle. Freeman (1967) developed a mathematical model to determine the gain in speed of a multiplier based on two design parameters, the maximum number of shifts per cycle and the maximum number of available multiples of the multiplicand. The higher the maximum number of shifts per cycle, the greater the speed gain.
A variable multiplier is also called a radix multiplier. It reduces the length of the product and makes it more efficient. It also produces less partial products. A radix multiplier can also be made more efficient by increasing the coding of the radix. However, a radix multiplier requires more complicated coding to produce the desired results.
The radix-r coded multiplier is an improved design for speed variable systems. This type of multiplier has a smaller amount of parts and lower power consumption. It also minimizes error due to its n-bit estimation and new variable error compensation techniques. By minimizing error, this variable multiplier reduces the number of steps in the computation of a variable.

Variable multiplier arrangement

Variable multiplier coding is a technique for reducing the number of partial products generated by a multiplier. This technique allows for the radix–8 number to be expressed as a fraction instead of a whole number. This method can provide superior results to radix–4 or radix-3 coding. In addition, variable radix multiplier coding can simplify the hardware realization process.
Variable multiplier circuit 30 can be configured to have a binary sequence of gain factors K1=1, K2=2, K3=4, K4=8, K5=16, etc., and can be configured to vary the capacitance of the multiplier between CREF and 15CREF in equal steps.
In addition to fast multiplication, variable radix multiplier coding also enables reducing partial products. This technique is also useful for solving sequential problems. Its flexibility allows it to handle large volumes of data in a short amount of time. This method is based on a novel concept of concurrent partial products.
In this study, we introduce a truncated multiplier, which has a small relative error of 2.03%. This method is faster than the precise multiplier. The proposed method achieves this by reducing the number of parts and applying new variable error compensation techniques. Detailed comparison results are shown in Section 7.
Variable multiplier arrangement for speed variable comes with its share of drawbacks. Its main disadvantage is that it requires a large amount of computational resources. It is not recommended for real-world use. Fortunately, it is possible to simulate the multiplier arrangement and optimize its functionality to improve the performance of the motor.
