Product Description:

The 20BM090BBDT0 is an AC servo motor designed for industrial automation by Sanyo Denki Co. This servo motor functions with precision to power CNC systems and automation systems as well as robotic machinery. It delivers a power output of 0.9 kW, which suits applications needing moderate-load capabilities.

The 20BM090BBDT0 servo motor runs using a 200 VAC three-phase power supply and operates at 50/60 Hz rated frequency. The servo motor operates at 3000 RPM as the rated speed parameter. It can achieve a maximum speed of 5000 RPM. The motor creates a steady torque output of 2.86 Nm to support operating needs during dynamic situations. Peak torque extends beyond 6.3 Nm, which is useful for short-term overloads. A precise position sensing option is included with an incremental optical encoder that forms part of the motor system. The encoder achieves 2500 measuring pulses throughout each revolution cycle. The 20BM090BBDT0 servo motor functions with a 5 VDC voltage and works with typical motion controllers. Differential line drivers offer noise-resistant signal transmission on the output of the encoder system. The product meets insulation level F, which allows exposure to temperatures of up to 155°C inside the unit. The motor operates best between 0°C to 40°C for ambient temperatures. The component exhibits humidity resistance within 20% to 80% when measured as non-condensation levels to prevent water-induced destruction.

The 20BM090BBDT0 servo motor performs without degradation between 0 to 1000 meters elevation. The JIS B 3502 classifies this motor for industrial use as it resists vibration. This mechanism helps maintain stability when the motor runs within vibrating equipment systems. The IP44 rating protects the motor against environmental dust while also preventing water from entering. The motor features a built-in thermal protection circuit that stops motor overheating risks.

Frequently Asked Questions about 20BM090BBDT0:

Q: How does the IP44 rating benefit the 20BM090BBDT0 servo motor?

A: The IP44 rating protects the 20BM090BBDT0 motor against solid particles over 1mm and splashing water, ensuring reliability in moderately harsh environments.

Q: Why is peak torque over 6.3 Nm beneficial in the 20BM090BBDT0 motor?

A: The peak torque capability of over 6.3 Nm in the 20BM090BBDT0 motor supports short-term load surges without performance degradation.

Q: How does the 2500-pulse encoder enhance the performance of the 20BM090BBDT0 servo motor?

A: With 2500 pulses per revolution, the 20BM090BBDT0 encoder allows high-resolution position control, ideal for applications needing precise motion feedback.

Q: Why is a thermal protection circuit important in the 20BM090BBDT0 motor?

A: The thermal protection circuit in the 20BM090BBDT0 motor prevents overheating damage by automatically shutting down during temperature surges, preserving motor life.

Q: Why is insulation class F critical in the 20BM090BBDT0 servo motor?

A: Insulation class F allows the 20BM090BBDT0 motor to withstand internal temperatures up to 155°C, preventing insulation breakdown in continuous-duty cycles.
