BOSCH motor Germany BOSCH model BOSCH price

BOSCH motors are a type of motor that changes speed by altering the number of magnetic pole pairs, voltage, current, frequency, and other parameters to achieve higher performance. Due to their excellent performance, adjustable-speed motors are widely used in industrial sectors such as steel, power plants, cables, chemicals, petroleum, cement, textiles, printing and dyeing, papermaking, and machinery for stepless speed control of loads with constant torque or decreasing torque. They are particularly suitable for driving pumps and fans with significant flow variations, achieving good energy-saving results.

BOSCH motor precautions

Motor precautions: 1. Before disassembly, use compressed air to blow off dust from the motor surface and wipe away dirt. 2. Select a location for motor disassembly and clean the site environment. 3. Familiarize yourself with the motor's structural features and maintenance technical requirements. 4. Prepare the tools (including special tools) and equipment required for disassembly. 5. To further understand defects during motor operation, perform an inspection test before disassembly if conditions permit. For this, run the motor under load and carefully check the temperature, sound, vibration, and other conditions of each part. Test voltage, current, speed, etc., then disconnect the load and perform a no-load inspection test separately to measure no-load current and no-load losses, keeping records. 6. Cut off the power supply, remove external motor wiring, and keep records. 7. Use a megohmmeter with appropriate voltage to test the motor insulation resistance. To compare with the insulation resistance value measured during the previous maintenance to judge the trend and state of motor insulation, convert insulation resistance values measured at different temperatures to the same temperature, generally converted to 75℃. 8. Test the absorption ratio K. When the absorption ratio is greater than 1.33, it indicates that the motor insulation has not been dampened or the dampness is not severe. To compare with previous data, also convert the absorption ratio measured at any temperature to the same temperature.

BOSCH motor applications

Variable frequency speed control for motors has become the mainstream speed control solution and can be widely applied to stepless speed transmission in various industries. Especially with the increasingly wide application of variable frequency drives (VFDs) in industrial control, the use of variable frequency motors has also become more widespread. It can be said that due to the superiority of variable frequency motors over ordinary motors in variable frequency control, wherever VFDs are used, variable frequency motors are commonly seen. The social benefits of domestically produced high-voltage variable frequency devices are significant, mainly including energy saving, thereby conserving resources and reducing environmental pollution. They eliminate starting shocks to motors and impacts on the power grid, reduce failure rates of motors and equipment, and improve control precision and automation levels. The economic benefits of variable frequency speed control are also very significant. For pumps and fans, fluid flow is proportional to the first power of speed, torque is proportional to the square of speed, and power is proportional to the cube of speed. As speed decreases, motor power consumption drops by the cube, so the energy-saving effect of variable frequency speed control is very significant. If flow decreases, speed decreases, head decreases, and motor power consumption decreases, theoretically saving energy. If dampers or valves were originally used for regulation, flow decreases while head increases, and motor power decreases; thus, variable frequency speed control saves more energy than damper or valve regulation. In addition to energy saving and efficiency improvement, there are some indirect economic benefits for different loads, mainly including improved power factor, realization of soft start, reduction of electrical and mechanical damage to the motor from starting torque, and smooth, stable, high-precision control.

BOSCH motor classification

Motors are divided into reactive and Sawyer types. The Sawyer linear stepper motor consists of a stationary part (called the reaction plate) and a moving part (called the mover). The reaction plate is made of soft magnetic material with uniformly distributed teeth and slots. The motor mover consists of permanent magnets and two coil-carrying magnetic poles A and B. The mover is supported by an air cushion to eliminate mechanical friction during movement, ensuring smooth motor operation and improving positioning accuracy. The maximum moving speed of this motor can reach 1.5 m/s, acceleration can reach 2g, and positioning accuracy can reach 20 microns. Two Sawyer linear stepper motors assembled perpendicular to each other form a planar motor. By supplying different combinations of control currents to the motors in the x direction and y direction (Figure 3), the motor can move in any geometric trajectory within the plane. Large automatic plotters are new devices combining computers and planar motors. Planar motors can also be used in laser cutting systems, with control precision and resolution reaching tens of microns.
