Three-phase asynchronous compact drives
Three-phase asynchronous compact drives
VEM compact drives feature robust grey cast iron motors and optimized drive electronics, designed for high vibration strength and sound design. They are available in standard construction types with high protection levels (IP 54 or higher), suitable for variable motor speed applications to enhance technological processes.
- No additional space required for switch cabinets.
- High vibration strength and protection level (at least IP54).
- Reduced project planning and installation time due to integrated components.
- Cost savings in materials and labor due to simplified installation and operation.
- Easy parameter adjustment and immediate operability.
The VEM compact drives are available in two main series:
- Series M21 ... T: Ranges from 0.55 to 7.5 kW, vector controlled, with integrated motor cooling.
- Series M21 ... VS: Ranges from 5.5 to 22 kW, vector controlled, with separate ventilation systems.
For Series M21 ... T:
- Supply voltage: 380 to 480 V ± 10% 3AC, frequency: 50/60 Hz ± 2%.
- Maximum current for 60 seconds: 160%.
- Protection type: IP 55 (IP 66 optional).
- Speed range varies by pole count (e.g., 2-pole: 0 to 7920 min-1).
- Pulse frequency adjustable up to 14 kHz.
Data is provided for different pole drives (2-pole, 4-pole, 6-pole, 8-pole) with specifications on nominal power, speed, torque, and current requirements.
Detailed dimensions and construction types (IM B3, IM B5, etc.) are provided for various models, ensuring compatibility with existing installations.
The document outlines specifications for various motor types, including three-phase standard motors, squirrel-cage motors, slip-ring motors, and single-phase asynchronous motors. Key specifications include shaft height, power output, basic speeds, and modifications such as foot and flange design, dual-speed, dual-voltage, and explosion protection.
The inverter is equipped with an independent ventilation system and allows speed adjustment without an external control panel. It supports various interfaces, including RS 485 and bus connections, and offers multiple digital and analogue inputs and outputs with customizable parameters.
The document references compliance with radio noise suppression standard EN 61800-3 + A11 and specifies protection types such as IP 54 and IP 55. It also mentions energy-saving motors according to CEMEP and EPAct.
For optimal performance, the document suggests using high-speed design versions for frequency ranges above 60 Hz. It also highlights the importance of thermal winding protection and the use of PTC thermistors.
The document provides detailed technical data for the M21 series, including supply voltage, frequency range, speed range, pulse frequency, and ambient temperature conditions. It also includes performance characteristics for 2-pole and 4-pole drives, with data on nominal power, speed, torque, and efficiency.
Dimensional drawings and construction types such as IM B3, B5, B35, and auxiliary types are provided. The document details cable entry sizes and ambient conditions for operation and storage.
The range includes compact drives, helical gear motors, adjustable gear motors, and special drives for applications like cranes and marine equipment. The document also mentions three-phase asynchronous generators and motors for mechanical smoke and heat exhaust ventilators.
Contact details for VEM motors GmbH and VEM motors Thurm GmbH are provided, including addresses, telephone numbers, fax numbers, and email addresses.

Advantages of compact drives The basis of VEM compact drive are two components, the robust VEM grey cast iron motor and a drive electronic that is optimised for motor operation. When thinking about the engineering design, the most importance was attached to a high vibration strength of the inverter and a sound design of the whole drive unit. Whereas the inverters of the design series M21...T will be cooled by the ventilator of the motor, the inverters of the design series M21... possess a separate ventilation system. The compact drives are available in all standard types of construction, similar...

Compact drives of series M21 ... T 0.55 to 7.5 kW (vector controlled design) For this design variation the cooling of the inverter is integrated in the cooling system of the motor, that means the cooling will be done by the ventilator of the motor or if necessary by an axially mounted forced-ventilation unit of the motor. Due to favourable motor connection of the inverter and the small dimensions, the mounting space of the standard asynchronous motor will be exceeded only slightly. The special product advantages of this design variation are: • type of protection IP 55, IP 66 as option • easy...
