Description

MAJOR MODIFICATIONS

Electric motors of the EM-07 series have the following modifications:

EM-07-ER – standard version with combined air cooling, built-in encoder, temperature sensor and basic specifications. Priorities are low price and maximum import substitution while ensuring high specific characteristics.

EM-07L-ER is a version with improved or maximum specific characteristics compared to standard EM-07-ER modules. Priority – high or limiting specific characteristics in its class (specific torque or specific power). Limited import substitution for the Russian Federation, since imported materials and components are used to obtain the best specific characteristics. As a rule, they are produced in limited quantities due to the relatively higher cost of products of this modification.

Basic equipment:

The basic package of EM-07-ER includes:

  • electric motor EM-07-ER;
  • built-in encoder with 2m cable;
  • built-in temperature sensor;
  • instruction for connection and operation;
  • shipping package

Options:

  • adapter insert for a propeller according to the customer’s request;
  • Additional temperature sensor.
