Italian UNIMEC motors, German and Italian UNIMEC models, Italian UNIMEC prices

Italian UNIMEC motors are motors that can be used in flammable and explosive environments without generating electric sparks during operation. Explosion-proof motors are mainly used in coal mines, oil and natural gas, petrochemical, and chemical industries. In addition, they are widely used in textiles, metallurgy, urban gas, transportation, grain and oil processing, papermaking, pharmaceuticals, and other sectors. As main power equipment, explosion-proof motors are typically used to drive pumps, fans, compressors, and other transmission machinery.

Structure of Italian UNIMEC motors

This motor component consists of an internal gear ring and a matching gear or rotor. The internal gear ring is fixed to the housing. Oil entering through the oil port pushes the rotor to revolve around a central point. This slowly rotating rotor drives the output via a splined shaft, forming a cycloidal hydraulic motor. After the introduction of this initial cycloidal motor, decades of evolution led to the formation of another concept of motor. This type of motor installs rollers within the built-in gear ring. Motors with rollers provide higher starting and running torque; the rollers reduce friction, thereby improving efficiency, allowing the output shaft to produce stable output even at very low speeds. Changing the direction of input and output flow allows the motor to reverse quickly and produce equivalent torque in both directions. Each series of motors offers various displacement options to meet different speed and torque requirements.

Classification of Italian UNIMEC motors

Based on the power supply, motors are divided into DC motors and AC motors. AC motors are further divided into single-phase and three-phase motors. Based on structure and working principle, motors are classified into DC motors, asynchronous motors, and synchronous motors. Synchronous motors are further divided into permanent magnet synchronous motors, reluctance synchronous motors, and hysteresis synchronous motors. Asynchronous motors are divided into induction motors and AC commutator motors. Induction motors are further divided into three-phase asynchronous motors, single-phase asynchronous motors, and shaded-pole asynchronous motors. AC commutator motors are divided into single-phase series-wound motors, AC/DC universal motors, and repulsion motors. DC motors are classified into brushless DC motors and brushed DC motors based on structure and working principle. Brushed DC motors are divided into permanent magnet DC motors and electromagnetic DC motors. Electromagnetic DC motors are further divided into series-wound, shunt-wound, separately excited, and compound-wound DC motors. Permanent magnet DC motors are divided into rare-earth, ferrite, and AlNiCo permanent magnet DC motors. Based on starting and running methods, motors are classified into capacitor-start single-phase asynchronous motors, capacitor-run single-phase asynchronous motors, capacitor-start-run single-phase asynchronous motors, and split-phase single-phase asynchronous motors. Motors are also categorized as drive motors and control motors. Drive motors include those for power tools (including drilling, polishing, grinding, slotting, cutting, reaming, etc.), home appliances (including washing machines, electric fans, refrigerators, air conditioners, recorders, VCRs, DVD players, vacuum cleaners, cameras, hair dryers, electric shavers, etc.), and other general small mechanical equipment (including various small machine tools, small machinery, medical devices, electronic instruments, etc.). Control motors include stepper motors and servo motors. Based on rotor structure, motors are divided into squirrel-cage induction motors (formerly known as squirrel-cage asynchronous motors) and wound-rotor induction motors (formerly known as wound-type asynchronous motors). Based on operating speed, motors are classified into high-speed, low-speed, constant-speed, and variable-speed motors. Low-speed motors include gear reduction motors, electromagnetic reduction motors, torque motors, and claw-pole synchronous motors. Variable-speed motors are classified into stepped constant-speed, stepless constant-speed, stepped variable-speed, and stepless variable-speed motors, as well as electromagnetic variable-speed, DC variable-speed, PWM variable-frequency variable-speed, and switched reluctance variable-speed motors. The rotor speed of an asynchronous motor is always slightly lower than the synchronous speed of the rotating magnetic field. The rotor speed of a synchronous motor remains at synchronous speed regardless of load size. 1. Horizontal vibration motor: (1) Loosen the fastening screws of the protective cover and remove the protective covers at both ends; (2) For vibration motors with excitation force less than MV50-2, MV50-4, MV50-6, MV30-8 (excluding these four specifications), the outer eccentric block is an adjustable block with a scale indicating the maximum excitation force percentage on the surface, and the inner eccentric block is a fixed block; both are pressed onto the motor shaft using fastening bolts. Reference lines are engraved on both end faces of the shaft. Loosen the fastening bolts of the outer eccentric blocks on both sides, rotate the outer eccentric blocks in the same direction to align the engraved line on the shaft with the excitation force scale line on the outer eccentric block, adjust to the required excitation force, tighten the fastening bolts of the outer eccentric blocks, and install the protective cover; (3) Excitation force greater than or equal to MV50-2;

Mechanical characteristics of Italian UNIMEC motors

Due to their low starting current and high starting torque, these motors are often used in locations where starting is difficult, or in mechanisms requiring high starting torque with intermittent instantaneous operation, such as for operating control switches. This allows for high starting torque and the selection of much smaller dimensions compared to other types of motors. Additionally, AC/DC universal motors have a wide speed regulation range and can achieve high speeds. Generally, the speed of an asynchronous motor depends on the number of poles and the supply frequency; for a 50Hz supply, the maximum speed of a two-pole motor is lower than 3ooor/min. Of course, variable-frequency motors can increase speed but require a dedicated power supply. Speed can be increased by reducing the number of armature conductors; for example, AC/DC universal motors for power tools reach speeds of 9900 to 145oor/min, and high-speed centrifuges for medical devices can reach maximum speeds of 20000r/min. Therefore, this type of motor is suitable for applications requiring high speed, such as dental drills driven by AC/DC universal motors. The mechanical characteristics of AC/DC universal motors are relatively soft; as torque increases, speed drops rapidly, limiting the increase in output power and making it difficult to overload due to increased load. They are suitable for constant power control applications or places where load torque changes significantly. For example, in the constant tension structure of tape recorders and bicycle transmission mechanisms, this type of motor can replace permanent magnet DC motors. When the load is very small, the speed of an AC/DC universal motor becomes very high, so it cannot operate at full voltage with no load. Generally, when operating at full voltage, the minimum load should not be less than 25% to 30% of the rated value. When the load is very small, the speed of an AC/DC universal motor becomes very high, so it cannot operate at full voltage with no load. Generally, when operating at full voltage, the minimum load should not be less than 25% to 30% of the rated value.
