Engine speed regulator

For smooth operation of engines without jumps, speed regulators are used. The models are produced on 12, 24 and 220 V. The principle of the equipment operation is based on changing the engine clock frequency. By type of construction, thyristor, transformer, pulse and triac versions are distinguished.

By the method of installation distinguish stationary and mobile devices. Also on the market you can find built-in modifications. In order to understand the models in more detail, the standard regulator scheme should be considered.

Model outline

A conventional regulator of constant engine speed includes a transformer of a down-type and a rotary controller. Rectifiers are used with a block of capacitors. Bandwidth is around 5.5 microns. If we talk about modifications to 12 V, then they use a kenotron. In this case, insulators are installed to safely operate the equipment.

Make a device yourself

Make a regulator of their own hands is quite simple. First of all, a controller is selected for it. The easiest way for a DC motor is to use rotary modifications. In stores, they are sold immediately with modulators. The transformer is installed with high capacity. After that, it is important to do the insulators. To adjust the motor of an alternating current, a dinistor is used.

Thyristor regulators

Thyristor speed controller of the engine, as a rule, is produced with high throughput. In this case, rectifiers are used in the operating type. Models are installed in some models. The sensitivity index for them depends on the output voltage of the motor. Stabilizers in many devices with a protection system.

The maximum permissible temperature of the regulators is 45 degrees. Expanders are only used for AC motors. It is also important to note that modifications on resistors are on the market. Their distinctive feature is a long service life. However, it should be noted that such models are quite expensive.

Frequency Regulators

The frequency regulator is only able to operate in a circuit with alternating current. Contacts in this case are output to modulators. The device bandwidth parameter is 3.5 microns. The rectifier is installed in the operating type. Many manufacturers make devices with a protection system. The permissible overload indicator is around 3 A. In this case, the controllers are of the rotary type. Still on the market are sold digital modifications with displays. Some devices are equipped with double insulators for protection.

Transformer regulators

Transformer speed controller, as a rule, is produced for powerful engines. Relays for models are of high-voltage type. Directly rectifiers are used with condenser units. Many modifications have transceivers. They are necessary for lowering the clock frequency.

Expanders in the models are code and switched type. Resistors are used with an overlay. For self-assembly, the model can not do without a quality controller. Electronic modifications in this case to collect independently is problematic. It is also important to note that button controllers are rarely used. However, for three-stroke engines they fit well.

Pulse modifications

The impulse type regulator is operated with alternating current motors of different capacities. Rectifiers in devices are of the operational type. The transmission capacity of the models is at the level of 4 microns. In this case, the output voltage of the modification depends on the engine power. Modulators are used both orthogonal and non-condenser type.

Expansions in many models are missing. It is also important to note that output contacts are used to connect devices. Stabilizers are installed only in devices with repeat controllers. Electronic modifications of this type on the market are rare. It is quite difficult to assemble the model yourself.

Triac types of regulators

Triac controllers are quite common. They work on the principle of phase change in frequency. To date, there are many homemade devices. They are created on the basis of a non-condenser modulator with a relay. Resistors are used both as a tuning and pulse type.

Transceivers, as a rule, are not available in regulators of this type. It is also important to note that stabilizers of different sensitivity are installed for powerful models. On average, the conductivity parameter of the current is no more than 5 microns.

Models for fans

Devices for fans can be operated in a network with direct and alternating current. The indicator of the operating frequency of the circuit does not exceed 55 Hz. In this case, the triac versions are equipped with rectifier relays. Expanders are often used in the code type. Also for fans, transformer modifications are used. The parameter of the operating frequency of the circuit in this case does not exceed 50 Hz. To connect the speed controller, output contacts are set.

12 V devices

Regulators at 12 V are often made of frequency type. Devices with rotary controllers are manufactured on the basis of building resistors. On average, the current conductivity does not exceed 5 microns. In this case, the sensitivity of the relay depends on the engine power. Rectifiers are often used operational type. Some modifications are equipped with open-type resistors.

If we consider models with push-button controllers, then they always use a frequency kenotron. These overload devices can withstand a maximum of 4 A. However, in this case, much depends on the manufacturer.

Modifications to 24 V

For commutator and asynchronous motors, it is suitable for a 24 V speed regulator. The device circuit includes modular-type controllers. If we consider transformer modifications, then they have a relay, as well as a capacitor unit. Transistors are usually used as a broadband type. In some models, dinistors are used to reduce the frequency.

The regulators are connected via output contacts. It is also important to note that there are a lot of electronic modifications on the market. There are also built-in devices that differ in their compactness. In most models there are no stabilizers.

Devices for 220 V

Modifications to 220 V are produced most often of impulse type. Suitable devices for synchronous modifications are suitable. Such models can operate in a circuit with direct current. The operating frequency of the system does not exceed 60 Hz. In this case, the conductivity of the current depends on the sensitivity of the relay. Rectifiers are most often used in the operational type. Controllers are used as a rotary or push-button type. It is also important to note that the market has many mobile modifications. Thyristors are of a semiconductor type. On average, the conductivity is 6 μ. In this case, the dinistors are used with insulators.

Regulators HL-FS 1.6

The said regulator of the collector motor revolutions is made on the basis of a step-down transformer. The capacity of the model is equal to 5.7 microns. The relay is not in this case. Direct rectifiers are used in the operational type. There are no transceivers at the regulator. To reduce the working frequency, the kenotron is used.

In this case, the sensitivity of the modification depends on the engine power. The degree of protection is provided by IP 35. It is also important to note that the regulator of the collector motor HL-FS 1.6 is capable of withstanding large current overloads. The minimum permissible temperature is -10 degrees.

Regulators Bahcivan BSC / 2

The fan speed regulator Bahcivan BSC / 2 is sold with a single-pole transceiver. A feature of this model can be called a qualitative expander. Directly lowering the operating frequency occurs due to the kenotron. The speed of the engine is very smoothly regulated.

Speaking about the parameters, the current overload of the system is 3.5 A. In this case, the fan speed regulator has a throughput of 5.3 microns.
