Guangdong Pumbaaev Drive Technology Co., Ltd. products

The winding form of the motor gradually transitions from round wire to flat wire, with high slot filling rate, short ends, high power density and strong heat dissipation capacity.

The motor adopts new insulating materials and processes to meet the high switching frequency requirements of SiC controllers for increasingly high-speed motors.

The winding form of the motor gradually transitions from round wire to flat wire, with high slot filling rate, short ends, high power density and strong heat dissipation capacity.

PMSM permanent magnet synchronous motor is a type of permanent magnet motor that is widely used in electric vehicles. With 15% higher efficiency than induction motors, PMSM motors are the most power-dense traction motors.

Motor controller is the control unit that controls the motor to drive the whole vehicle, and belongs to the core components of electric vehicles. Motor controller has CAN communication function, over-current protection, overload protection, under-voltage protection, over-voltage protection, phase loss protection, energy feedback, power limit, high voltage interlock, fault reporting and other functions. The motor controller technology is relatively mature at present, it has the characteristics of high integration, high power density, long life, stable output, etc.

Microcontroller (MCU) plays a key role in electric vehicle motor control. They are the core components of the motor control unit, responsible for executing complex algorithms, monitoring sensor data, adjusting motor parameters, and communicating with other vehicle systems.

The Motor Control Unit (MCU) is an electronic module between the battery and the motor that controls the speed and acceleration of an electric vehicle based on the input of the switch. The controller converts the direct current of the battery into alternating current, and adjusts the power output of the battery to drive the motor. The controller can also reverse the rotation of the motor and charge the battery in reverse during regenerative braking. The Motor controller of electric vehicles can be broadly divided into the following categories, depending on voltage, power and current:

PPS500 4-in-1 Controller series four in one controller is designed for new energy buses, logistics vehicles, sanitation vehicles, oil pump, air pump and DC/DC. It integrates V/F and high performance open loop vector control algorithm and can be used to control the asynchronous motor and permanent magnet synchronous motor.
