Variable speed drives are also known as variable frequency drives, VFD’s, adjustable speed drives, and inverters. Variable speed drives are solid state motor control systems used mainly for industrial manufacturing. Variable speed drives are designed to control the speed of an electric motor. Variable speed drives can reduce energy costs up to 50% by speed reduction on applications where the full speed (RPM) of the electric motor is not required.
The energy saved on a utility bill from using a variable speed drive is often significant enough to pay for the variable speed drive within a couple of months from installation date. Variable speed drives are commonly used on pump, fan, and air compressor applications, and are often used in manufacturing facilities to increase or decrease the start up time on alternating current (AC) electric motors.
Increasing and/or decreasing the start up time on an AC current electric motor via a variable speed drive can add years to the motor’s overall lifespan. Using a variable speed drive can also improve efficiency on production demands. Variable speed drives provide the ability to control the frequency of starting and stopping an AC electric motor.This ability provides a means by which an AC electric motor is only operating when needed. AC electric motors have a longer lifespan if they are not continuously operating when they do not need to be.
The most common type of variable speed drive is known as a V/Hz (volts per hertz), and are applied to applications such as fans, pumps, air compressors, and other related applications wherehigh starting torque is not required. V/Hz variable speed drive applications typically do not require full torque when the AC motor is operating at less than the base speed (RPM) of the electric motor. V/Hz variable speed drives are the most inexpensive type of variable speed drive. V/Hz variable speed drives do not provide full motor torque at low RPM.
Open-Loop vector drives are also known as s”ensorless vector” variable speed drives. Open loop vector drives adapted the name “sensorless vector” because they do not use an external encoder for speed feedback to the motor.Open loop vector drives are used in applications where high starting torque and full torque at low speed (RPM) is required. Open-Loop vector drives operating a motor a zero RPM should not be used on crane or hoist applications. Most open-loop vector drives are used on CNC machines, mixers, mills, lathes, and other applications where high starting torque or full torque at low RPM is needed.Open loop vector drives are usually more expensive than a V/Hz variable speed drives.
Closed-Loop vector drives are used in applications where precise speed control (0.01%) is needed, or in applications where extensive programming is needed. Closed-Loop vector drives use an encoder on the motor to provide constant shaft position indication to the drive’s microprocessor. The encoder feedback allows the drive microprocessor to constantly control torque no matter how many RPM the motor is operating at. Closed-Loop vector drives are used to provide the motor to operate at full torque even at zero RPM. Closed-Loop vector drives are commonly used on hoist and crane applications because crane and hoist motors must produce full torque prior to it’s brake being released, or the load will drop and it will not be able to stop.

Lenze servo motors are designed for all applications requiring precision and dynamic performance. Lenze servo motors have been designed to communicate with Lenze servo drives.
The Lenze servo motor and servo drive combination results in precise motion control systems. Depending on the application and torque requirements, Lenze servo motors provide both asynchronous and synchronous motors.
Lenze MCS series servo motors rated torque range is 0.5 to 190 Nm; with power ratings from 0.25 kW through 15.8 kW. Lenze MCS servo motors are mainly used in applications that require high dynamic performance with minimal application space. The MCS stator winding is made up of individual coils using Single Element Pole Technology (SEpT). Lenze MCS servo motors are user friendly when combined with Lenze 9400 servo drives, and commissioning is “plug and play”, since the controller comes supplied with corresponding motor parameters.
High-Quality magnetic materials and specially developed pole forms in the MCS make for excellent servo drive technology.Lenze MCS servo motors are designed with reinforced bearings to protect the encapsulated stator and to increase reliability in harsh ambient conditions.Lenze MCS servo motors feature high overload capacity and large angular accelerations.
Lenze MCS servo motors can be quickly mounted and easily serviced because of their unique plug connections. The Lenze MCS servo motors come with a secondary loose nameplate and an electronic nameplate for ease of commissioning.
Lenze MCS servo motors can use either a resolver as feedback, incremental encoder or an absolute value encoder. Other features of the Lenze MCS include a hold brake option, natural or forced ventilation system, and IP65 enclosure (IP54 forced).
