Permanent magnet motors (PM) and, more specifically, the Interior permanent magnet motor (IPM) is far superior in many ways to the traditional induction motors that have dominated the market for the past 130 years. Nikola Tesla invented the induction motor in 1887 and its simplicity, robustness and ability to be powered directly off of the A/C power grid led to its widespread and near total market capture until the late 20th century.

While there are many types of induction motors and permanent magnet motors (radial flux vs. axial flux, for example) we will focus on the general benefits of IPM motors versus the traditional radial flux induction motor.

An induction motor must “induce” an electromagnetic force on both the rotor and the stator through copper windings to provide output torque. This means that a lot of copper is needed throughout the motor leading to a bulkier and heavier architecture than a PM motor. A PM motor utilizes only windings on the stator and magnets on the rotor. This reduces the weight and volume of the copper wire needed to create the same electromagnetic force of an induction motor of similar power.

The ability for the IPM motor to create much stronger magnetic fields than its induction counterpart are the primary reason for the power density difference. The strong and permanent nature of the magnets also allow for full torque at zero shaft speed, whereas an induction motor’s output torque drops off significantly as the output speed is lowered.

For hydraulic systems that place high demands on control engineering, servo pumps are the perfect solution. The basic version of these pump systems also consists of three main components:Servo inverter

Servo pumps control the pressure or the volume flow. They precisely convert electrical energy into the hydraulic energy that is currently needed in the system. The classic use of valves for control can be either completely or partially omitted. This considerably simplifies every hydraulic system.

Baumüller supplies innovative and optimized drive solutions for all sectors through years of intensive cooperation with mechanical engineers. Due to the integrated control unit in the converter, Baumüller servo pumps can easily be connected to your machine control systems. In the process, they reduce the energy consumption of your drive system significantly and also allow for shorter cycle times, greater accuracy as well as lower noise development. See for yourself and rely on the flexibility and power of innovation of the experts from Baumüller.

Servo pump drives for the hydraulic supply consist of a fixed displacement pump driven by a servo motor. The flow rate and pressure can be controlled precisely by highly dynamic changing of the motor speed. If neither flow rate nor pressure are required, the motor stops and does not consume any energy.

These production steps are highly differentiated, meaning that within one process step the injection molding machine has widely fluctuating output requirements. Closing and injection sequences require large quantities of hydraulic oil and a high volumetric flow. Cooling times, on the other hand, require no or just minimal output.

The difference in energy consumption can be clearly seen in the typical hydraulic system shown in the diagram. The high energy efficiency of the servo-hydraulic solution arises from a needs-specific pump output. When the machine is at rest, e.g. during cooling, then the motors will also be at rest and will consume no energy.

An additional example is presses. The cycle in the figure is divided into three partial cycles: lose press (compacting the material), dwell time, press back and handling. The comparison of energy consumption between the three different systems shows that the solution with a servo pump in the individual partial cycles has a significantly lower power input and thus has a significantly lower energy consumption overall. Unlike conventional hydraulic systems, only the energy that is actually needed is used, while in the classic systems the losses are higher due to the constant revolution of the standard motor in rest phases, such as when stopped (see figure).

Injection molding machines and presses are not the only applications for servo-motor pumps. The use of a servo-hydraulic system is a sensible option wherever phases with high power requirements alternate with pause times in the machine cycle, such as in stamping and bending machines.

The advantages of hydraulic power transfer and electric power setting using servo technology combined, as an alternative to hydraulic pressure and volumetric flow control, yields an energy-efficient and cost-effective solution in the form of a dynamically controllable servo pump.

As a special feature, Baumüller offers three different options for the connection between the pump and the motor. In the Standard Line, the attachment is made using the conventional solution of coupling and pump support. This tried-and-tested option can be achieved with a standard motor shaft and motor flange and is flexible due to the separate components. The second development stage, the Advanced Line, designates the direct attachment of the pump on the motor via internal toothing. Here, there is no need for a pump support and coupling, so the system is more compact and robust. Omitting the pump support as a resonating body also reduces the noise impact.

In the third stage, the Performance Line, the hydraulic fluid is additionally used for intelligent circulating oil lubrication. For this purpose, connections were added not only to the motor but also to the fixed displacement pump, allowing the leakage flow of the pump to be used for the permanent lubrication of the toothing. This eliminates an otherwise necessary grease lubrication of the internal toothing, which would be due every 3,000 operating hours on average, also rendering the system particularly robust. Baumüller thus offers a patent-pending solution, which leads to significantly reduced service costs in operation.

Permanent magnet synchronous motors are used as motors in servo-hydraulic systems. The main criterion for selecting servo motors is good performance in terms of dynamics and overload capacity.

Baumüller offers various motor series for use in servo-hydraulic systems, from the dynamic three-phase current servo motor DSD2 to the three-phase current synchronous motor DS2. All motors are available in an air-cooled and a water-cooled version. Size 45–132 servo motors are also available in an oil-cooled form. This is an advantage in the hydraulic system, since the oil is available in the machine anyway. Another advantage is that liquid-cooled motors have a higher power density and can therefore be dimensioned smaller.

Direct attachment is available for the Advanced and Performance Line models. The following motor-pump combinations are possible. The Standard line, attachment via coupling and pump support is possible with all the motors listed here.
