SUMER TRANSMISSIONS motors are machines used to convert mechanical energy and AC electrical energy into each other. Due to the tremendous development of AC power systems, AC motors have become the most commonly used motors. Compared with DC motors, AC motors have a simple structure, are easy to manufacture, are relatively robust, and can be easily made into high-speed, high-voltage, high-current, and high-capacity motors because they do not have commutators (see commutation in DC motors). The power range of AC motors is very wide, from a few watts to hundreds of thousands of kilowatts, or even millions of kilowatts. In the early 20th century 80s, the largest steam turbine generators had already reached 150 ten thousand kilowatts.

SUMER TRANSMISSIONS motor applications

Application of motors in precision machining: To improve productivity and enhance machining quality, ultra-high-speed and ultra-high-precision machining are key. Currently, the requirements for the feed speed of CNC machine tools have increased from 6 to 8m/min m/min to greater than 50 to 60m/min m/min, and the acceleration requirements have reached 1 to 5g. This indicator cannot be achieved by traditional feed drive systems with intermediate transmission and conversion links, so a new type of actuator needs to be found. This has led to the emergence of a new generation of linear motor feed drive systems. Since the end of the 20th century, the world's four major international machine tool exhibitions have shown that the direct drive of linear motors is increasingly being applied to CNC machine tools, machining centers, presses, etc., which is a trend. Linear motor drives have characteristics such as high thrust, high speed, high precision, and smooth feed motion. The machine tool feed system uses a linear synchronous motor for direct drive. The biggest difference from the original rotary motor transmission method is that the mechanical intermediate transmission link between the motor and the worktable (slide) is eliminated, i.e., the length of the machine tool feed transmission chain is shortened to zero, so this transmission method is called "direct drive," also known as "zero transmission." Direct drive avoids disadvantages such as backlash, inertia, friction, and insufficient rigidity in screw transmission, bringing performance indicators and advantages that the original rotary motor drive method could not achieve.

SUMER TRANSMISSIONS motor principle

The motor has two windings, namely the starting winding and the running winding. The two windings are spatially separated by 90 degrees. A large-capacity capacitor is connected in series with the starting winding. When the running winding and the starting winding are powered by single-phase AC, the capacitor causes the current in the starting winding to lead the current in the running winding by 90 degrees in time, reaching its maximum value first. Two identical pulsating magnetic fields are formed in time and space, generating a rotating magnetic field in the air gap between the stator and the rotor. Under the action of the rotating magnetic field, an induced current is generated in the motor rotor, and the interaction between the current and the rotating magnetic field produces electromagnetic torque, causing the motor to rotate.

SUMER TRANSMISSIONS motor mechanical characteristics

A motor, also known as an induction motor, is an AC motor that converts electrical energy into mechanical energy through the interaction of the rotating magnetic field in the air gap and the induced current in the rotor winding. It has a simple structure, is easy to manufacture, is inexpensive, operates reliably, is durable, has high operating efficiency, and has suitable working characteristics. Three-phase asynchronous motors are mainly used as motors to drive various production machinery, such as fans, pumps, compressors, machine tools, light industrial and mining machinery, threshers and crushers in agricultural production, and processing machinery for agricultural products, etc.
