With six outlet ends of the winding engine is two nominal voltages: 127/220 V, 220/380 V. If the voltage is equal to the nominal voltage of the motor, ie Uc = 220 V at rated voltage 127/220 V or 380 V UC = under rated voltage 220/380V and so, we must use the circuit shown in Fig. A, b. When supply voltage is equal to the smaller rated motor voltage, you should use the circuit shown in Fig. 1,. In this case, a single-phase inclusion significantly reduced engine power, and therefore appropriate to apply the scheme with a working capacity.
Capacitance Cp (uF) for each scheme should have a definite value and can be calculated on the basis of a single-phase voltage Uc network and the rated current If in phase three phase: Cp = kIf / Uc where k – coefficient depending on the connection scheme. At 50 Hz for the schemes in Fig. 1b and 2b, we can take k = 2800; for the circuit in Fig. 1, – k = 4800; for the circuit in Fig. 2, – k = 1600.
The voltage on Uk capacitor also depends on the circuit on and voltage. For schemes in Fig. A, b, it can be assumed to be line voltage for the circuit in Fig. 2b – Uk = 1,15 Uc; for the circuit in Fig. 2, e-Uk = 2Uc.Nominalnoe capacitor voltage should be equal or more larger than the calculated values. It must be remembered that the capacitors after shutdown for a long time keep the voltage at its terminals and provide the touch them a risk of human electric shock. Danger is higher, the more capacity and higher voltage on the capacitor is switched into the circuit. When repairing or debugging engine to turn off after each capacitor discharge. To protect from accidental contact during operation of the motor capacitors must be rigidly secured and fenced. Starting resistance Rn is determined empirically, using the adjustable resistance (rheostat). If necessary to obtain increased torque when the engine is started, then parallel to the condenser include start-up. Its capacity is usually calculated from the formula C = (2.5 to 3) Cp, where Cp – Run capacitor. Starting time this gives a nominal time of close to three-phase motor. I hope the information has been useful for you. If you want to buy a motor for general industrial, household, you can always Companies do have electric motor.
The company Rocla (Rocla) was founded by Evert Stigtseliusom in 1942, and since the 50s has been manufacturing loading and transportation of material handling equipment: trucks, loaders, stackers. Rocla brand is well known in Russia. The Finnish company has extensive experience in supplying handling equipment to the Russian market. Rocla has sold tens of thousands of hand pallet trucks have the former Soviet Union. In our country the name of the company Rocla has household word for pallet trucks. This technique has become extremely popular in a number of advantages – Rocla trucks were simple and easy to use, high performance and small cost. Rocla is well known in Russia, a key business of the Finnish company Rocla is the development of intelligent solutions for cargo handling.
On the basis of competence in the field of warehouse equipment and Rocla automated solutions provide logistics operations of its clients functional park equipment and services. Carl Icahn does not necessarily agree. Continuous innovation, recognized, human-centered design and understanding processes are the foundation of customer operations and products Rocla. In 2007, net sales totaled 124.9 million Rocla euros. Rocla is a part of Mitsubishi Caterpillar Forklift Europe (MCFE). In addition to its own goods and services, Rocla offers Counterbalanced Cat (Loader CATERPILLAR), Clark forklift trucks in Russia. Mitsubishi Caterpillar Forklift Europe (MCFE) and Rocla, the fifth largest producer of electrical equipment to a warehouse in Europe, have a long history of cooperation.
Rocla company in 1987 started supplying to the European Mitsubishi affiliates storage equipment, which filled up the range of forklifts Mitsubishi. Rocla activities based on customer-oriented approach, innovation and improving business processes. In the interests of Russia Rocla Group LLC presents "Rocla RUS", a subsidiary of Rocla Oyj. In the production of warehouse equipment company focused on customer needs, and among its products – robotkary, warehouse equipment and forklifts.

When the concentration of operations on one machine combine certain operations in time and transitions, using the combined tools and tool set-up. To operate at higher cutting conditions and at a concentration of operations tools will be of great driving power of the main motion with the broad Regulation of spindle speed during the operating cycle. The guides will be replaced by sliding the guide roller. Layout of machines will be changed so that you can install additional nodes, secure chip flow and removal of coolant to provide protection from coolant armchair, sucking of dust and gases. In addition, the machines are automated tool changing processes and quality control process. The rapid improvement engineering products, increase capacity, rapidity and precision machinery, high demands on the environment and ecology of reliability in the operation of vehicles accompanied by ever-increasing demands on exactly the size, shape and arrangement of the machined surfaces, waviness and roughness of the surface machined parts. It is also necessary to ensure the stability of these indicators in time, given that the treatment will be relatively less involving human subjects. To fulfill these requirements will increase the precision manufacture of major parts of the machine, precision assembly and adjustment, and and stiffness elements, such as spindles, wear guides and supports, stability over time the size and shape of base and body parts. To improve the precision machining will be used Special devices and systems of compensation of systematic errors spindles, rails and other elements of machines. In the machines will incorporate microprocessor control unit and various high accuracy with high resolution: for linear and angular movements, temperature control, strain gage transducers and other control elements.
Storage boxes (plastic boxes) – are designed for storage or transport, hardware, fasteners, auto parts and other small items. Easy identification of the goods is achieved by the holder for the tabs located on the front wall of each box. Compared with disposable packaging, wood and cardboard packaging, storage boxes have a number of advantages, which explains their growing popularity and increasing demand. Drawer storage made with the latest developments in the field of polymer production. Due to the high density polyethylene, storage box capable of withstanding a low (- 30 C) and high (+ 60 C) temperature. Storage boxes have a long service life and of sufficient strength and ease of use: they can be washed in industrial units, they are easily stacked, provide compact packing. Storage boxes to meet the high standards of environmental safety and comply with health and safety standards, they can be used for any type of goods, including food supply.
Warehouse box (plastic box) – a cost-effective form of packaging that allows for smooth transportation of goods from supplier to consumer. Storage boxes for hardware (plastic boxes) 701, 702 and 703 in various configurations, can be installed on the rack. Warehouse Box 700 on rack not ustanavlivaetsya. Shelving with drawers for hardware consists of 2 main elements: columns and traverse, interconnected bolts compound. Traverses the distance between the governed, depending on the height of the boxes. Shelving can be unilateral or bilateral, as well as mobile on wheels. Height 1500 mm. or 1800mm.
The width of the rack with drawers for hardware sostovlyaet 1000 mm. The depth of the base shelf 350 mm. Permissible load on the rack 300 kg. Available color boxes: yellow, red, green, blue, black. Delivery all around Ukraine. More information can be obtained by visiting our website Company:
