How Four-Quadrant Drive Works, And Its Impact On The Automotive Industry

If you’re in the automotive industry, then you’re undoubtedly familiar with Four-Quadrant Drive. It’s a common technology used in vehicles to help them achieve better fuel economy and lower emissions. In this blog post, we’ll take a look at what Four-Quadrant Drive is at GTake, its impact on the automotive industry, and some of the benefits it offers.

What is four-quadrant drive?

GTAKE PFQD four-quadrant AC drive can not only accurately and quickly simulate the required loading torque, but also feed the regenerated energy from the drive system back to the grid through its AFE unit, reducing electricity consumption without generating extra harmonic interference and offering remarkable energy saving in applications with frequent brakes, such as cranes, centrifuges, milling machines, motor mutual-towing and wind tunnel test systems, etc.

The advantage of PFQD series four quadrant AC drive

Unique switching frequency control technology reaches up to 1500Hz frequency output.

Isolated tunnel design for heat dissipation.

Support various encoder types.

Plentiful communications, RS485 / PN / EtherCat / Modbus TCP / CAN.

High power factor, PF ≥ 0.99.

Advanced PWM rectification technology is adopted on the active front end, which dramatically reduces the total harmonic distortion of current, THDi≤2.5%.

Strong overload capacity, 150% @ 1min.

Thorough system protections.

Speed adjustment range: 1:1000, Speed control accuracy: ±0.02%.

Torque respond time:< 5ms; Torque control accuracy:  ±3%.


The four-quadrant drive is a technology that has had a significant impact on the automotive industry in recent years. Allowing drivers to control their vehicles in different directions, it has made driving much more enjoyable and practical. Additionally, it has allowed for new car models that are designed to be safer and more reliable. With so many benefits to the four-quadrant drive, it is no wonder that this technology continues to grow in popularity.
