The Differences Between CZPT and EP

A mechanical Speed Variator is a common piece of equipment in the industry. If you’re in the market for one, there are several options to choose from, including the CZPT and the EP. Here is a look at the differences between these three units and how they differ from one another.


A EP Speed Variator allows you to adjust the speed of the video signal to change the way it looks and sounds. It is designed to be easy to use, and it can be installed in a variety of different ways. It is a perfect tool for television producers and other industries that require the speed of video signals to change.


The CZPT AHM Speed Variator is an effective tool for varying speed and torque of motors. It has a compact design and long life span. It transmits torque with the help of a fixed star wheel. Other features of this product include high stability, abrasion resistance, and toughness.


CZPT Speed Variators feature stepless operation and a large ratio range. They are light and compact, and have an aluminum die-cast gearbox. They are also durable and suitable for continuous operation. They provide smooth, accurate speed adjustments and are extremely quiet in operation. They can be used for a variety of applications, including automotive, papermaking, rubber, plastic, and pharmaceutical machinery.
CZPT Speed Variator is available in five sizes and is equipped with an IEC motor (B5 type). Variator output speeds are easily adjusted using a control handwheel, which features a direct speed position readout. Variable speed output can also be monitored through a proximity sensor.


CZPT is a company that was originally founded to manufacture friction-type Variable Speed Drives and later expanded to include Helical Inline Gear Reducers. The company uses modern CNC machining centres to ensure that the components are of the highest quality. The company also uses premium-grade materials for the components. For example, its gears are made of 18 Ni Cr Mo5 steel. The casing and flanges are made of grey cast iron Q 250 UNI ISO 185. The output shafts are made of 18 Ni Cr Mo5 or 39 Ni Cr Mo3.
The CZPT AV2 Speed Variator uses a two-piece friction-based transmission system to achieve variable speed. A friction cone is mounted on the motor shaft and a friction ring is mounted on the transmission shaft. The two components are connected by a dog-clutch cam. The friction between the two components is maintained through the use of a small, low-pressure spring. This allows the speed of the CZPT AV2 to be adjusted even when the machine is in motion.


CZPT AV3 Speed Variators are widely used for industrial applications. Its features include compact size, high durability, and integrated design. It also comes with a life span of five to ten years and features a simple structure invention. The CZPT AV3 Speed Variator is also known for its stability, abrasion resistance, and toughness.
