Customer Success Stories

Water Treatment Plant C

Water & Wastewater | Pump Station VFD Retrofit

Challenge

The municipal water treatment plant needed to retrofit 12 pump drives (75kW each) with variable frequency drives to reduce energy consumption. The existing fixed-speed pumps were wasting energy through throttling valves. The solution needed to be reliable, easy to maintain, and compatible with the existing SCADA system.

Solution

Installed Oriental-based VFDs using OIM200-12E4 IGBT modules in NEMA 12 enclosures. The drives featured built-in PID control for pressure regulation, eliminating the need for external controllers. Energy-saving algorithms optimized pump operation for varying demand conditions. RS485 Modbus communication enabled integration with the existing SCADA system.

Results

The VFD retrofit achieved 35% average energy savings, reducing annual electricity costs by $45,000. The pressure control improved system stability, reducing water hammer and pipe stress. Payback period was 18 months. The plant has reported zero drive failures in 3 years of operation.

Manufacturing Company D

Industrial Manufacturing | Machine Tool Spindle Drive

Challenge

The customer needed high-performance spindle drives for CNC machine tools requiring 15kW continuous power with 150% overload for heavy cutting. The drives needed precise speed control, fast dynamic response, and high reliability for 24/7 production environments.

Solution

Developed a custom spindle drive solution using Oriental OIG75N120H discrete IGBTs in a compact design. The control system featured sensorless vector control with 150% starting torque and fast torque response. Advanced thermal management and protection features ensured reliable operation. The design included EMI filtering to meet industrial EMC standards.

Results

The spindle drives achieved ±0.01% speed accuracy and 50ms torque response time. Machine productivity increased 20% due to faster acceleration and higher cutting speeds. The drives have operated continuously for over 2 years with no unplanned downtime. Customer reported improved surface finish quality on machined parts.

Frequently Asked Questions

What is the difference between V/f control and vector control in the industrial drive solution?

V/f (Volts per Hertz) control maintains a constant ratio between voltage and frequency, providing simple speed control suitable for pumps, fans, and conveyors. It offers good efficiency at rated speed but limited torque at low speeds (typically 20-30% at 5Hz). Vector control (sensorless or with encoder) provides independent control of torque and flux, enabling 150% starting torque at 0.5Hz and precise speed control. Vector control is required for high-dynamic applications like machine tools, cranes, and high-performance conveyors. The Oriental solution supports both modes - use V/f for simple applications and vector control for demanding applications.

Use V/f control for pumps, fans, and simple conveyors; use vector control for machine tools, cranes, and high-dynamic applications.

How do I size the IGBT modules for my industrial drive application?

To size Oriental IGBT modules for industrial drives: First, determine the motor rated current from the motor nameplate or calculate from power and voltage (I = P / (V × √3 × η × pf)). Second, apply an overload factor - for standard duty, use 1.5x rated current

for heavy duty, use 2x rated current. Third, select an IGBT module with current rating equal to or greater than the overload current. For example, a 30kW 380V motor has rated current of approximately 57A

with 150% overload (85A), select OIM200-12E4 (200A) which provides good margin. Consider also the switching frequency - higher frequencies may require derating.

Size IGBTs at 1.5-2x motor rated current for overload capability. Contact our FAE team for detailed sizing calculations.
