Portable alternators from Mecc Alte

Mecc Alte T16F and T20F

Designed to be exceptionally versatile, these portable products are manufactured to be suitable for all applications where an easy transportable energy source is needed. The portable alternators are available with a 50 or 60Hz frequency, all with 2 poles ranging from 1–18kVA available either as single bearing or as twin bearing with a double support. In order to couple them to a prime mover it is possible to choose among a wide range of shafts, flanges and couplings. The 2 pole rotors have a damper cage and the stator windings have a shortened pitch to reduce the harmonic content. The single phase units are designed brushless and have a high operating reliability. Minimal maintenance is required as there are no collectors or sliding contacts. The three phase range is designed with brushes and a slip ring and is transformer-controlled. This enables a high pick-up capacity ideal for motor start applications.

Good performances with a single phase connection

Mecc Alte BTP3

The generators of this series are three-phase, with brushes and they are characterised by a compound-type regulation on the 3 phases; they have a high pickup capacity (motors startup: 1 HP X KVA). They have also good performances with a single phase connection: with the delta connection it is possible to obtain 70 % of the three phase rated load and 45 % star connection with neutral. This series of 2 Pole Alternators have the stator or the rotor inclined in order to improve the wave form. The 2 pole rotors have a damping cage and all the windings of the stator have a shortened pitch to reduce the harmonic content.

The generators of this 4 Pole Alternator series are three-phase, with brushes and they are characterised by a compound-type regulation on the 3 phases; besides a high pickup capacity (motors startup: 1 HP X KVA) they also provide good performances under a single phase connection. With the delta connection it is possible to obtain 70 % of the three phase rated load and 45 % star connection with neutral. This series of 4 Pole Alternators have the stator or the rotor inclined in order to improve the wave form. The 2 pole rotors have a damping cage and all the windings of the stator have a shortened pitch to reduce the harmonic content.

Available as 2- and 4-pole

Mecc Alte ECP3

The ECP3 range has many product features designed into the alternator. Self-regulation is obtained through a digital electronic regulator that is fed by an auxiliary winding. We guarantee an almost constant supply from the generator – under any possible operating condition. The windings have a 2/3 pitch in order to reduce the harmonic content of voltage.

The entire series is manufactured according to, and complies with, the most common specifications such as CEI 2-3, IEC 34-1, EN 60034-1, VDE 0530, BS 4999-5000, CAN/ CSA-C22.2 No14-95- No100-95.

Fail safe operation

Mecc Alte ECSO

The ECSO generators are brushless with a rotating field with salient poles and damping cage; static skewed armature with shortened pitch winding. The system is basically a three phase compound design, with the possibility of inserting the electronic AVIR by means of a simple connector. No modification or extra setting of the control system is required because the AVIR is a bi-directional electronic regulator capable of adding or subtracting excitation depending upon the needs of the machine. The unique feature of this regulation system is to provide fail safe operation.

When and if the AVIR fails the machine automatically reverts to its compound regulation system guaranteeing continuous function. The AVIR also provides protection against under speed, by reducing the voltage in relation to the speed, when the speed falls below 10% of the nominal. Thereby avoiding the dangers of overheating in the inductor when in a reduced speed situation.

A very wide product range developed as a result of experience

Mecc Alte ECO/ECP

The versatility of our products and their robust design means that our ECO and ECP series are formed to meet the requirements of industry and the high technological specifications of applications. They are available either as single bearing or as twin bearing with a double support. In order to couple them to a prime mover, it is possible to choose among a wide range of flanges and couplings.

All alternators consist of a fixed stator with skewed slots and a rotating inductor fitted. In addition, models above 15kVA are fitted with a damper cage as standard. All alternator windings have a 2/3rd pitch in order to reduce harmonic content.

The generators manufactured by Mecc Alte are in compliance with the CEI 2-3 file 11111 national standard. This Italian standard corresponds to the European standard EN 60034-1 and to the international standard IEC 60034-1; it is related also to the British standard BS 4999 Part 101; it is equivalent to the German standard VDE 0530 Part 1, and it is included in the French standard NF 51.111. Mecc Alte generators meet also the requirements of international ISO 8528-3 standard (Reciprocating internal combustion engine driven alternating current generating sets – Part 3: Alternating current generators for generating sets) and the requirements of NEMA MG 1-2011 (Motors and Generators).
