Bonfiglioli Transmission and Automation Product Selection Reference

P "high torque density option: The LC/LCK/SL series can choose the" P "option, which can increase torque by up to 40% while achieving miniaturization, reducing acceleration mass, and improving energy efficiency.

Installation method: All precision series are designed to be installed in any direction, without worrying about lubrication issues (lifelong lubrication).

Input adaptation: All series offer flange/coupling kits that are compatible with mainstream servo motors in the market, reducing the need for transitional component designs.

Industrial motor product line

Bonfiglioli provides a complete matrix from universal AC motors to high-efficiency IE3, single-phase, and DC motors.

BN/M series: Universal IEC motor, 0.06~30 kW, 2/4/6/8 pole and multi speed versions, equipped with inverter duty as standard, brake can be powered by DC/AC (including quick release rectifier).

BE/ME series: IE2 high-efficiency motor, 0.75~22 kW, meets IEC 60034-30 standard, also suitable for frequency conversion.

BX/MX series: IE3 ultra efficient motor, 5.5~22 kW (4-pole), reflecting a commitment to environmental sustainability.

BS series: single-phase induction motor, 0.06~1.5 kW, with running capacitor, optional starting capacitor to increase starting torque, suitable for household and light industrial equipment.

BC series: Permanent magnet DC motor, torque 0.3~4.5 Nm, powered by 12~180 Vdc, IP54 protection, suitable for battery powered or DC speed control systems.

Engineering Tip: All AC motors come with thermistor (PTC) and thermostat protection options, as well as independent forced cooling (for low-frequency long-term operation) and encoder (incremental line drive or push-pull). Explosion proof certification (ATEX) also applies to some BN/BE specifications.

Servo motor product line

Bonfiglioli's servo motors are mainly designed for high dynamic and high-precision positioning applications.

BMD series: Permanent magnet synchronous servo motor, using Salient Pole technology, neodymium iron boron magnetic steel, locked rotor torque of 0.85~125 Nm, rated speed of 1600~6000 min ⁻¹. Feedback supports rotary transformer (8/10 kHz), EnDAT 2.1 absolute encoder (single/multiple turns), and Hiperface. Protection level IP65/IP67.

BTD series: Compact servo motor with a locked rotor torque of 0.26-27 Nm, emphasizing small size and low temperature rise, with a protection level of IP65 (optional IP67).

BCR series: High performance servo motor, locked rotor torque of 0.2~115 Nm, with extremely high instantaneous overload capacity, suitable for heavy-duty servo applications.

Key selection points:

Select the matching feedback method based on the drive type (such as Active Cube supporting rotary and EnDAT/Hiperface) to ensure closed-loop compatibility.

For situations that require safe braking, 24 Vdc electromagnetic brake can be integrated (hold braking, non dynamic braking).

Inverter and Drive Family

Bonfiglioli's frequency converters cover both simple and servo driven types, seamlessly integrating with their own motors.

AGILE series: economical sensor vector frequency converter, 0.12~11 kW, supports asynchronous motors and permanent magnet synchronous motors (sensorless). Built in Safe Torque Off (STO), MMC memory card, integrated Modbus, and multiple fieldbus options. Suitable for applications that are cost sensitive but require vector performance.

ACTION series: Universal system driver, 0.55~132 kW (ACT401 covers high power up to 132 kW), as detailed in the previous article (ACTION 401/201 series).

Active Cube Series: Drivers for high-end servo and motion control, 0.25~132 kW (ACU401) and Size 8 (160~400 kW, including ACU601 690V level). Equipped with 32 programmable motion blocks, 36 zeroing modes, absolute/relative positioning, Touch Probe, Teach In and other functions, it can directly control servo motors such as BMD/BCR, and complete complex single axis movements without the need for an external PLC.

VCB series: high-power universal frequency converter, 132-800 kW, suitable for large equipment such as fans, pumps, compressors, etc., with optional protection level of IP54.

S2U series: Compact mini frequency converter, 0.20-2.2 kW, V/F control, built-in PID and 8-speed, suitable for simple speed control applications (such as small conveyor belts and packaging machines).

HMI and software tools

BMI series human-machine interface: three sizes of 3.5 ", 7", and 10 ", IP65 front panel, standard Ethernet interface, optional fieldbus (Profibus, CANopen, etc.). Can be combined with the built-in PLC function of Agile/Active Cube to build a compact control system that does not require an independent PLC.

VPlus software: Bonfiglioli's unified driver programming, monitoring, and diagnostic platform. Support parameter setting, oscilloscope (KP232 required), logic programming, remote diagnosis, and motion block configuration.

Collaborative suggestions for engineering selection

During the project design phase, it is recommended that engineers follow the following process:

Clearly define the load conditions: torque speed curve, duty cycle (S1~S10), ambient temperature, protection level, and whether there is a risk of explosion.
