A motor is provided. The motor includes a cooling system configured to cool a stator having a core wound around by a coil, wherein the cooling system includes oil holders installed on a side under the stator in an inner space of a motor housing and provided to allow oil to be collected up to a level capable of allowing at least some of a lower end section of the stator to be immersed for cooling.

Motor provided with cooling system

An oil temperature increasing system and method for an eco-friendly vehicle includes: an oil-temperature detector configured to detect a temperature of oil flowing to a motor and a transmission by an electric oil pump; and a controller configured to receive a detection signal of the oil-temperature detector, and apply a current for increasing temperature to the motor when the oil temperature is less than a predetermined reference temperature. A temperature of the motor is increased by the current applied to the motor, such that the oil temperature is increased by heat of the motor.

Oil temperature increasing system and method for eco-friendly vehicle

A rotor sleeve provides a direct cooling method in which oil flows into the rotor sleeve via a flow passage formed through an input shaft of a transmission and is distributed to a motor coil of a driving motor to cool the motor coil. The rotor sleeve has a flow passage structure capable of maintaining a balance between the amount of oil to be distributed toward a transmission and the amount of oil to be distributed toward an engine.

The present disclosure relates to a driving motor for environmentally friendly vehicles. The driving motor for the vehicles includes: a stator core; a bobbin assembled to the stator core; a coil part wound on the bobbin; a coil lead-out portion configured such that an end portion of the coil part drawn from the bobbin is formed to have a curved structure; and a terminal bonded with a bonding portion formed in the coil lead-out portion.

Driving motor for environmentally friendly vehicles

A charging system of an electric vehicle is provided and is implemented based on a motor and an inverter which are previously mounted within the electric vehicle, without a separate on-board charger. The charging system includes a DC power supply that is configured to store or output DC power and a motor that is configured to drive the electric vehicle. An inverter drives the motor based on a flow of current and an AC power supply outputs the AC power. Additionally, a charging relay is configured to perform a switching operation to supply DC power output from the inverter to the DC power supply and an input relay is configured to perform the switching operation to supply the AC power to the inverter.

Charging system of electric vehicle

A charging device for an eco-friendly vehicle includes a charger having an electronic switching element which reduces an excessive current instantaneously flowing when an external AC power source outside the vehicle is connected to the charger; and a controller configured to control an operation of the electronic switching element.

According to the present disclosure, there are provided a method of determining which one of first and second input signals Rez+ and Rez&#x2212; is shorted to ground based on a magnitude of a Lissajous signal, a method of determining which one of first and third output signals Sand Sis shorted to any one of the first and second input signals Rez+ and Rez&#x2212; based on an average magnitude value of the third output signal S, and a method of determining which one of second and fourth output signals Sand Sis shorted to the first input signal Rez+ based on an average magnitude value of the fourth output signal S.

Method of detecting wiring mismatch of resolver

A method for controlling an on-board charger (OBC) of an eco-friendly vehicle can widen the range of an AC input power frequency at which the charging operation of the OBC is possible without increasing the capacity of a power factor correction (PFC) capacitor. According to the method, an increase in output voltage ripple of the PFC capacitor is suppressed by sensing an AC input voltage frequency and then performing variable control of decreasing output power of the OBC based on the sensed frequency, i.e., a variable control of decreasing the output power of the OBC as the AC input voltage frequency decreases, so that the range of the AC input power frequency at which the charging operation of the OBC is possible can be extended without increasing the capacity of a PFC power element.
