Lauer GmbH motor Germany Lauer GmbH model Lauer GmbH price

Lauer GmbH motors are a new generation of gear reduction motors, featuring compact size, low noise, maintenance-free operation, and an attractive appearance. The speed ranges from 0.83r/min to 300r/min. This series of low-speed motors is a new high-tech product that integrates electromagnetic drive and reduction mechanism within the motor housing. The low speed and high torque can directly meet customer requirements without the need for additional reduction devices. The motor uses Class B and Class F insulation, with protection ratings of IP44 and IP55, and voltages of 220V and 380V.

Lauer GmbH motor operating principle

The starting and operation of the motor are formed by the interaction of the magnetic fields generated by the stator windings, the rotor squirrel-cage windings, and the permanent magnets. When the motor is stationary, a three-phase symmetrical current is supplied to the stator windings, generating a rotating stator magnetic field. This rotating stator magnetic field induces current in the squirrel-cage windings relative to the rotor, forming a rotating rotor magnetic field. The asynchronous torque generated by the interaction between the rotating stator magnetic field and the rotating rotor magnetic field accelerates the rotor from standstill. During this process, the difference in speed between the rotor's permanent magnet field and the stator's rotating magnetic field produces an alternating torque. When the rotor accelerates to a speed close to synchronous speed, the speeds of the rotor's permanent magnet field and the stator's rotating magnetic field become nearly equal. The slightly higher speed of the stator's rotating magnetic field interacts to produce torque that pulls the rotor into synchronous operation. In synchronous operation, no current is generated in the rotor windings. At this point, only the permanent magnets on the rotor generate a magnetic field, which interacts with the stator's rotating magnetic field to produce driving torque. Thus, it can be seen that the permanent magnet synchronous motor relies on the asynchronous torque of the rotor windings to start. After starting is complete, the rotor windings no longer play a role, and the driving torque is produced by the interaction of the magnetic fields generated by the permanent magnets and the stator windings.

Lauer GmbH motor applications

Motors are mainly used in digital control systems, offering high precision and reliable operation. If position detection and speed feedback are employed, closed-loop control can also be achieved. 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. They are also used in industrial automation production lines and printing equipment. A stepper motor is an open-loop control element that converts electrical pulse signals into angular or linear displacement. Under non-overload conditions, the motor's speed and stopping position depend only on the frequency and number of pulse signals, and are not affected by load changes. That is, when a pulse signal is applied to the motor, the motor rotates by one step angle. The existence of this linear relationship, combined with the fact that stepper motors have only periodic errors and no cumulative errors, makes controlling stepper motors very simple in fields such as speed and position control. 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, power drive circuits, etc., to operate. Therefore, using stepper motors effectively is not easy; it involves extensive professional knowledge in mechanics, motors, electronics, and computers. Nowadays, there are indeed many manufacturers producing stepper motors, but very few have professional technical personnel capable of independent development and research. Most manufacturers have only ten to twenty employees and lack even the most basic equipment, remaining at a stage of blind imitation. This causes many troubles for users in product selection and usage. 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 users in product selection, usage, and overall machine improvement.

Lauer GmbH motor operating principle

Motor Working Principle: A servo mechanism is an automatic control system that enables output controlled variables, such as an object's position, orientation, and state, to follow any change in the input target (or setpoint). servo positioning relies mainly on pulses. Basically, it can be understood that when the servo motor receives 1 pulse, it rotates by the angle corresponding to 1 pulse, thereby achieving displacement. Because the servo motor itself has the function of emitting pulses, every time the servo motor rotates by an angle, it emits a corresponding number of pulses. This forms a response, or closed loop, with the pulses received by the servo motor. In this way, the system knows how many pulses were sent to the servo motor and how many pulses were received back, allowing for very precise control of the motor's rotation and thus achieving precise positioning, which can reach 0.001mm. DC servo motors are divided into brushed and brushless motors. Brushed motors have low cost, simple structure, high starting torque, wide speed regulation range, and easy control. They require maintenance, but maintenance is inconvenient (carbon brush replacement), and they generate electromagnetic interference, imposing requirements on the environment. Therefore, they can be used in cost-sensitive general industrial and civil applications. Brushless motors are small in size, light in weight, high in output, fast in response, high in speed, low in inertia, smooth in rotation, and stable in torque. Control is complex, but intelligentization is easy to achieve. Their electronic commutation method is flexible, allowing for square wave or sine wave commutation. The motors are maintenance-free, highly efficient, operate at low temperatures, have very low electromagnetic radiation, and have a long service life, making them suitable for various environments. AC servo motors are also brushless motors, divided into synchronous and asynchronous motors. Synchronous motors are generally used in motion control. They have a wide power range and can achieve very high power. They have high inertia and low maximum rotational speed, which decreases rapidly as power increases. Therefore, they are suitable for applications requiring smooth low-speed operation. The rotor inside the servo motor is a permanent magnet. The U/V/W three-phase electricity controlled by the driver forms an electromagnetic field. The rotor rotates under the action of this magnetic field. At the same time, the encoder built into the motor feeds back signals to the driver. The driver compares the feedback value with the target value and adjusts the rotation angle of the rotor. The precision of the servo motor is determined by the precision (line count) of the encoder. Functional differences between AC servo motors and brushless DC servo motors: AC servo is better because it uses sine wave control, resulting in small torque ripple. DC servo uses trapezoidal waves. However, DC servo is simpler and cheaper.
