DC electric motor
KE/KH-KG
GROSCHOPP
The goals at the start of this re-design were set as follows:
• Enhancing the power spectral density
• Improving the electromagnetic compatibility \(EMC\)
• Reducing the brush-wear
• Reducing manufacturing variances
• Reducing manufacturing cost
The new models of field-wound commutator-motors made by Groschopp AG comprises 6 different type sizes\.
• KE / KH 44
• KE / KH 50
• KE / KG 70
• KE / KG 80
• KE / KG 87
• KE / KG 94
The first classification letter stands for the motor-manufacturing-principle \(K: field-wound commutator-motor\), the second classification letter stands for the model-construction \(E: skeleton-type motor, G: housed motor, H: hand-motor\), while the number following the two classification letters gives the outside-diameter in mm of the pole-ring stack\.
The higher power spectral density of the new models can either be used for performance at a higher output-torque, or else – using the same torque as before – the volume of the motor can be reduced\.
