Electric Motor (Electromechanical)

Product Specifications

Technical details and manufacturing context for Electric Motor (Electromechanical)

Definition

This electric motor is a component used in industrial machinery, typically as the prime mover within a hydraulic or electromechanical actuator. It provides the primary rotational force that drives the actuator's mechanical output, such as a lead screw or gear train, to produce linear or rotary motion for positioning, clamping, or force application. The motor operates on the principle of electromagnetic induction: when an electric current passes through its windings within a magnetic field, a Lorentz force is generated, causing the rotor to turn. This rotational motion is then transferred to the actuator's drive mechanism.

Typical materials include electrical steel laminations for the core, copper windings, an aluminum alloy housing, and permanent magnets such as neodymium. The motor is available in a range of specifications that must be selected based on the application's load and speed requirements. Key parameters include rated power from 0.75 to 250 kW, rated voltage from 220 to 690 V AC, rated speed from 750 to 3000 r/min, efficiency class from IE2 to IE4, insulation class from F to H, degree of protection from IP54 to IP65, operating temperature from -20 to 40 °C, relative humidity up to 95% (non-condensing), frame size from 63 to 355 mm, mounting types IM B3 to IM B5, noise level from 55 to 85 dB(A), and weight from 5 to 1500 kg. These values are reference ranges and must be verified for the specific model and application.

Relevant standards include IEC 60034-1 for rating and performance, IEC 60038 for voltages, IEC 60034-30-1 for efficiency classes, IEC 60085 for insulation, IEC 60529 for protection, IEC 60072-1 for frame sizes, IEC 60034-7 for mounting, and IEC 60034-9 for noise. These standards serve as procurement and verification references; they do not imply certification or compliance of any specific product. Always confirm model-specific values and standards with the legal manufacturer or supplier.

Working Principle

The motor operates on electromagnetic induction. When an electric current flows through the stator windings, it creates a rotating magnetic field. This field interacts with the rotor (which may have permanent magnets or induced currents), producing a Lorentz force that causes the rotor to turn. The rotational torque and speed are determined by the motor's design and the applied electrical supply. The motor's output shaft is then connected to the actuator's drive mechanism, such as a lead screw or gear train, to convert the rotary motion into the desired linear or rotary output for industrial positioning or force application.
