Intensity limiter

The Intensity Limiter for Speed Variator is a device that regulates the power to the motor by limiting the intensity of the starting current. This device employs a substantial portion of the variator elements and is low-cost and space-efficient. It also works at low current and power levels.

Capacitor C

The Speed Variator is composed of two main components, a rectifier module and a capacitor. The rectifier module provides the DC voltage bus and is located upstream of the inverter module. The ballast capacitor 29 is situated between the two. Both the components work together to regulate the output voltage.
The voltage across the capacitor is applied through the potentiometer P. When the current is greater than the voltage across the resistor R 4, it results in a positive half-cycle. At this point, the current from point A polarizes the Zener diode Z, which has a conduction threshold of 100 volts. In the meantime, the capacitor C continues to be charged through the potentiometer P at a constant current. Moreover, the resistance R 4 is adapted to determine the charging current required to maintain the minimum motor speed.
Another type of Speed Variator is an overspeed protection device. This device protects the motor from an overload by limiting the motor current. This component also limits the output voltage when the motor is started. This design requires low currents and low powers and reduces the overall cost of the device. In addition, it also ensures that the motor operates at low speeds. This means that the voltage at the output of the Variator should be lower than the voltage at the motor.

Protection circuit CP

The Speed Variator is a device that controls motor speed by adjusting a potentiometer. During normal operation, the motor can run at one half of the supply voltage or both half-cycles at high speeds. The speed regulation is automatic and the transition between these modes is seamless. In the present invention, the motor is protected from overloads by incorporating a circuit CP, which serves as a second shunt circuit for charging the capacitor C. The circuit CP requires a -ve voltage that represents the current in the motor during negative half-cycles.
The Speed Variator protection circuit CP includes two transistors with opposite polarity and common emitter configurations. The transistors are connected through their common collector resistors R 15 and R o. The transistors are protected by the circuit through diode D 3. Diode D 3 is connected in series with resistor R 16 and is connected to the junction point of the capacitor C and the resistor R o. The common collector resistor R 16 regulates the +ve voltage of the measuring circuit CM.

Mechanical continuous gear variator 100

A mechanical continuous gear variator 100 is a type of transmission that has multiple gears. This type of transmission includes a first shift element B1, a second shift element K1, and a third shift element C2. The first shift element B1 has a clutch or brake, while the second shift element is either a gear or a sprocket.
Mechanical continuous gear variators can be used to change the speed of an engine. This type of gearbox can be attached to a milling machine or a drill. A mechanical continuous gear variator 100 can be attached to the drive shaft of one device, while a second device can be connected to the driven shaft of another device. By adjusting the speed of the second device, the mechanical continuous gear variator 100 can make it faster or slower, and reduce or increase the amount of work needed to finish the task.
Mechanical continuous gear variator 100 comprises two groups of multiplier gears 50, 60. The drive shaft 1 is rotatably mounted on a frame 13, and the driven shaft 9 is rotatably mounted on carriage or rails. The movable translation means are coupled to adjustment means, which adjust the position of the movable translation means.
Mechanical continuous gear variator 100 functions as a variable multiplier, wherein the first group of gears performs the first multiplication and the second group performs the second. These groups then multiply the same amount, giving double the final multiplication. The ratio between the drive shaft 1 and the driven shaft 9 is 1:1. The final ratio is greatest when the carriage 10 is at its maximum translation distance.
Mechanical continuous gear variator 100 implements three shift modes. The first range, V1, is the first range. The second range, V2, is the second range. The third range is the third range. These three modes are implemented by selectively controlling the shift elements of transmission device 100. The shift elements open and close alternately at the speed-synchronized point.
