Transmotec motor Germany Transmotec model Transmotec price

Transmotec motors are permanent magnet motors commutated or controlled by electronic circuits. Permanent magnet brushless motors come in two types: sine wave drive and square wave drive. Those driven by rectangular wave current are commonly referred to as permanent magnet brushless DC motors, while those driven by sine wave current are commonly referred to as permanent magnet AC servo motors. Based on sensor type, they can be classified into sensor-equipped motors and sensorless motors.

Transmotec motor applications

Motors offer advantages such as simple structure, ease of manufacturing, low cost, and reliable operation, but their power factor is relatively low (less than 0.5), and efficiency is also lower. The power of reluctance synchronous motors generally ranges from a fraction of a watt to hundreds of watts. They are commonly used in automatic control devices, physical instruments, movie projectors, electrostatic copiers, and other equipment. Reluctance synchronous motors have a simple structure, low cost, and reliable operation, and are widely used in automatic and remote control devices, recording fax machines, and the clock industry. An AC motor whose operating speed maintains a constant ratio to the frequency of the connected power supply. During operation, the motor speed is always equal to the synchronous speed, which is the origin of the term "synchronous motor." Synchronous motors are widely used in high-power production machinery that does not require speed adjustment, such as large air compressors, crushers, blowers, and motor-generator sets, with powers reaching several kilowatts or even tens of thousands of kilowatts. Compared to asynchronous motors of the same capacity, high-power synchronous motors have distinct advantages: high power factor, and the ability to operate at a leading power factor by adjusting the excitation current, which helps improve the grid's power factor; high-power, low-speed synchronous motors have a smaller volume. Synchronous motors can be classified into salient-pole and non-salient-pole types based on rotor structural characteristics, with most being made as salient-pole types. If classified by the fixed position of the magnetic poles, there are rotating armature types (where the magnetic poles are fixed on the stator, with a three-phase AC winding nested on the rotor, connected to the external circuit via slip rings and brushes on the shaft) and rotating field types (where the magnetic poles are fixed on the rotor), with most being made as rotating field types. The magnetic poles of synchronous motors are generally excited by DC current; some use permanent magnets and are called permanent magnet synchronous motors. A synchronous motor operating in motor state without a mechanical load, only providing or absorbing reactive power from the grid, is called a synchronous condenser or synchronous compensator, used to improve grid power factor and maintain grid voltage levels.

Transmotec motor principle

A stepper motor is an open-loop control component that converts electrical pulse signals into angular or linear displacement. Under non-overload conditions, the motor's speed and stopping position depend solely on the frequency and number of pulses, unaffected by load variations; specifically, each pulse signal causes the motor to rotate by one step angle. The existence of this linear relationship, combined with the characteristic that stepper motors exhibit only periodic errors without cumulative errors, makes speed and position control using stepper motors very simple. Although stepper motors are widely used, they cannot be used under conventional conditions like ordinary DC or AC motors. They require a control system composed of dual-ring pulse signals and power drive circuits to operate. Therefore, effectively utilizing stepper motors is not easy, as it involves extensive professional knowledge in mechanics, electrical engineering, electronics, and computing. Currently, while there are many manufacturers producing stepper motors, very few possess specialized technical personnel capable of independent development and research. Most manufacturers have only ten to twenty employees and lack even the most basic equipment, operating merely at a stage of blind imitation. This causes considerable trouble for users in product selection and application. In view of the above situation, we have decided to take the widely used variable reluctance stepper motor as an example to describe its basic working principle, hoping to assist a broad range of users in selection, application, and overall machine improvement.

Stepper motors are primarily used in digital control systems due to their high precision and reliable operation. Closed-loop control can also be achieved if position detection and speed feedback are employed. Stepper motors have been widely applied in digital control systems, such as in digital-to-analog conversion devices, CNC machine tools, computer peripheral equipment, automatic recorders, and clocks, as well as in industrial automation production lines and printing equipment.
