 All electric vehicles have at least one traction motor, so the market for electric vehicle traction motors is one of the largest markets for electric vehicle parts and a primary determinant of the performance and affordability of a given vehicle. Indeed, IDTechEx Research find that in 2013 44.6 million electric motors will be needed for vehicles, rising to 147.7 million in 2023. 
   
 Today, the motors that propel electric vehicles on land, through water and in the air are mainly brushless because brushed commutator motors are on the way out. Most of the number and the value of those brushless traction motors lies in permanent magnet synchronous ones, notably Brushless DC ""BLDC"", a form with trapezoidal waveform, and Permanent Magnet AC ""PMAC"", a type with a sinusoidal...

Trimethylopropane (TMP) Market - Global Industry Analysis, Size, Share, Growth, Trends And Forecast 2014 - 2020
By - Transparency Market Research
Trimethylopropane (TMP), is an organic compound which contains three hydroxyl functional groups. It is a white crystal in its solid state and when melted it is a transparent liquid. TMP is a hygroscopic compound and should be stored carefully in order to avoid moisture absorption. This compound is readily soluble in water, alcohol and in acetone. It is a very stable compound and does not cause any specific danger to the environment. TMP is usually manufactured in the form of semi transparent white flake and when melted forms a transparent melted liquid. TMP finds its use in...
Cryosurgery Market - Global Industry Analysis, Size, Share, Growth, Trends And Forecast, 2014 - 2020
By - Transparency Market Research
Cryosurgery is the application of extremely low temperature to destroy abnormal tissue. The technique has been successful in treating some types of cancers and skin diseases. Extreme low temperature for cryosurgery is achieved through use of liquid nitrogen or argon gas. For treatment of external conditions, liquid nitrogen is applied to the diseased skin cells with help of a cotton swab or spraying devices can also be used. For treating internal conditions, liquid nitrogen or argon gas is passed through hollow probes, which are efficiently guided by MRI or ultrasound. Cryosurgery has been...
Anti-Infectives Market - Global Industry Analysis, Size, Share, Growth, Trends and Forecast, 2012 - 2018
By - Transparency Market Research
Anti-infective agents are drugs used for the purpose of killing and/or suppressing the infection causing organisms from invading the host organism by means of its replication or releasing variety of toxins in the host. Such infection causing micro-organisms include viruses, bacteria, fungi, viroids and macro parasites. Infections thus caused can be classified depending on the type of organism causing infection and the symptoms and medical signs shown by host.  The global market for anti-infectives is classified by product type as antifungal, antiviral and antibacterial...
