The 2.2kW Insert-Type Electric Motor is designed for driving hydraulic pumps in compact hydraulic power units and industrial machinery. The motor uses an insert-type shaft connection structure that allows direct connection with compatible hydraulic pumps, helping reduce installation space and simplify the assembly process between the motor and hydraulic pump.

The motor has a rated power of 2.2kW (approximately 3HP) and is suitable for hydraulic applications requiring a compact and practical power transmission solution. It can be widely used in hydraulic pump stations, machine tools, manufacturing equipment, and industrial hydraulic systems.

Key Features

The 2.2kW insert-type motor offers the following advantages in hydraulic pump installation applications:

• 2.2kW rated power: Provides mechanical driving force for compatible hydraulic pumps.
• Insert-type shaft connection: Allows the input shaft of a matching hydraulic pump to be connected through the motor-side drive interface.
• Compact installation: Helps reduce the installation space required for the motor and hydraulic pump combination.
• Improved coaxiality: A properly matched direct connection structure helps maintain coaxiality between the motor and hydraulic pump.
• Reduced connecting components: In compatible configurations, a separate external coupling can be eliminated.
• Flexible installation: Suitable mounting configurations can meet the structural requirements of different hydraulic power units.
• Hydraulic pump compatibility: Can be used with some hydraulic gear pumps and other hydraulic pumps using compatible connection structures.

These features make the 2.2kW insert-type motor a practical choice for hydraulic systems with certain requirements for installation space and power transmission reliability.

Working Principle of Insert-Type Hydraulic Pump Motors

The insert-type motor drives the connected hydraulic pump by converting electrical energy into mechanical rotational power.

Traditional motor and hydraulic pump combinations usually require a separate coupling and pump bracket, while the insert-type motor uses a matching internal drive connection structure.

The input shaft of the hydraulic pump is inserted into the corresponding drive connection interface on the motor side, allowing the rotational power of the motor to be transmitted to the hydraulic pump.

When the motor starts, the rotating shaft drives the hydraulic pump. The hydraulic pump then delivers hydraulic oil to the system according to its own displacement, operating speed, and the actual working conditions of the hydraulic circuit.

The actual connection structure depends on the motor model, hydraulic pump shaft structure, and mounting interface.

A properly matched motor and hydraulic pump combination can simplify the installation process and help reduce coaxiality problems caused by additional connecting components.

Advantages of Insert-Type Motors in Hydraulic Systems

Compact Motor and Hydraulic Pump Combination

One of the main advantages of the insert-type motor is its compact installation structure.

In compatible assembly solutions, by reducing additional connecting components, the motor and hydraulic pump can be mounted more closely together.

This feature is particularly suitable for hydraulic power units with limited installation space.

Simplified Installation Process

Traditional hydraulic pump installation may require a separate coupling, pump bracket, and additional coaxiality adjustment steps.

When the motor and hydraulic pump have matching mounting interfaces, the insert-type connection can simplify the overall assembly process.

Reliable Power Transmission

Correct shaft connection fit and coaxiality help transmit the mechanical power output of the motor stably to the hydraulic pump.

Proper installation can reduce unnecessary vibration and mechanical stress caused by connection misalignment.

Convenient Hydraulic System Integration

Insert-type motors can be used in compact hydraulic power units and hydraulic pump assemblies.

Their connection structure provides hydraulic equipment manufacturers who need to save installation space with more motor and hydraulic pump combination options.

Application Areas

The 2.2kW insert-type motor is suitable for various industrial hydraulic applications.

Hydraulic Power Units

Provides mechanical driving force for compatible hydraulic pumps installed in compact hydraulic power units.

Hydraulic Pump Stations

Provides power support for hydraulic pump stations in industrial equipment and hydraulic control systems.

Machine Tool Equipment

Suitable for machine tool hydraulic systems requiring compact motor and hydraulic pump combinations.

Industrial Manufacturing Equipment

Provides hydraulic pump driving power for hydraulic systems in manufacturing machinery and automation equipment.

Hydraulic Clamping Systems

Suitable for hydraulic pump assembly units that power corresponding hydraulic clamping circuits.

Equipment Maintenance and Replacement

Can be used as a replacement motor for hydraulic equipment when the rated power, electrical parameters, shaft connection structure, and mounting dimensions are consistent with the original equipment.

How to Select a Suitable 2.2kW Insert-Type Motor?

Selecting a suitable motor cannot be judged only by rated power.

The following key technical parameters should also be checked before installation.

Rated Power

The nominal rated output power of this motor is 2.2kW.

The motor power actually required by the hydraulic system depends on the hydraulic pump displacement, working pressure, rotational speed, and overall efficiency.

The selected motor must be able to provide sufficient driving power for the expected hydraulic working conditions.

Voltage and Frequency

Confirm the power supply voltage and frequency required by the equipment.

Different motor models may be suitable for different power supply systems.

The actual voltage, number of phases, and frequency must match the equipment power supply.

Motor Speed

Motor speed directly affects the output flow of the hydraulic pump.

Before selecting a replacement motor, confirm the required speed and motor pole configuration.

Shaft Connection Structure

The insert-type shaft connection interface must match the input shaft of the hydraulic pump.

Key dimensions to confirm include the internal drive connection form, shaft diameter, keyway or spline structure, and effective insertion length of the shaft.

Mismatched connection structures may cause assembly difficulties or mechanical damage.

Mounting Dimensions

Check the motor mounting flange, bolt hole positions, centering spigot diameter, and related connection dimensions.

Even with the same rated power, different motors may use different mounting interfaces.

Hydraulic Pump Compatibility

Confirm the compatibility between the motor and the selected hydraulic pump.

Some insert-type motors may be specifically configured for certain hydraulic gear pump series, such as some GPY series or other hydraulic pumps with compatible interfaces.

Whether direct installation is possible cannot be judged only by the hydraulic pump series name; the actual shaft connection structure and mounting dimensions must be verified.

Working Cycle and Operating Conditions

Confirm the motor’s rated duty, ambient temperature limits, cooling method, and expected load conditions.

The selected motor must be suitable for the actual operating cycle of the hydraulic equipment.

Installation and Maintenance Recommendations

Correct installation and regular maintenance are very important to ensure reliable operation of the 2.2kW insert-type motor.

• Check shaft connection compatibility: Confirm that the motor drive interface matches the hydraulic pump input shaft.
• Confirm installation coaxiality: Ensure that the mounting flange and locating surfaces are correctly aligned.
• Check electrical connections: Confirm that voltage, number of phases, frequency, and wiring method meet requirements.
• Avoid overload operation: Ensure that the driving power required by the hydraulic pump does not exceed the rated output capacity of the motor.
• Maintain good heat dissipation: Ensure that motor ventilation and cooling channels are unobstructed.
• Monitor operating temperature: If the motor overheats abnormally, check it promptly.
• Check vibration and noise: Abnormal noise or vibration may indicate incorrect installation or mechanical faults.
• Check connecting components: Check the connection status between the motor and hydraulic pump during regular equipment maintenance.

Before maintenance, disconnect and isolate the power supply, and ensure that the hydraulic system has been safely depressurized.

Regular inspection helps reduce unexpected equipment downtime and extend the service life of the motor and hydraulic pump assembly.
