The Journey of Motorama EV Private Limited: From Repair to Manufacturing Excellence
Delhi-based Motorama EV Private Limited, an IIT Delhi incubated startup, began its journey in 2021 with a vision to impact the electric vehicle domain significantly.
Starting with the repair and maintenance of BLDC motors and controllers, we gained invaluable experience in identifying and rectifying failures, training our workforce, understanding the supply chain, and learning about various motor designs and materials. This period also helped us build a strong network within the industry
By 2023, we had repaired over 2,500+ motors and 1,500+ controllers, serving more than 35 clients across India and completing over 10 job works for leading manufacturers and institutes. This experience gave us a deep understanding of prevalent issues and solutions, positioning us well for the next phase of our journey.
We expanded into manufacturing BLDC motors, focusing on electric vehicles and HVAC sectors. Leveraging our knowledge and experience, we started designing our own motors. Notably, we developed rare-earth-free motors under the Grant scheme at IIT Delhi, including a 12-inch, 1-kilowatt rear hub motor with 19.5Nm rated torque and 65Nm peak torque, specifically for the EV market.

Failure causes:
BLDC motors and controllers in electric vehicles can fail due to several common causes.
A) Motor failures often stem from:
🔹 Overheating, bearing issues, electrical overload, vibrations, moisture and poor-quality components.
🔹 Driving practice of using brake while accelerating also causes motor failure
🔹 Roads terrain
🔹 Overheating and electrical overload damage insulation and windings, while bearing failures and vibrations lead to mechanical damage. Moisture and contamination cause corrosion and short circuits.
B) Controller failures are usually due to over-voltage, under-voltage, over-current, environmental factors,
software issues, component failures, improper installation, and thermal overload
Comprehensive Testing for BLDC Motors and Controllers
At Motorama, we ensure the highest standards of performance and reliability for BLDC motors and controllers through rigorous diagnostic and performance tests. These include:
Diagnostic Tests for BLDC Motors
🔹 Visual Inspection → Identify physical damage or wear.
🔹 Insulation Resistance Test → Check motor insulation integrity.
🔹 Winding Resistance Test → Detect discrepancies in motor windings.
🔹 Back EMF Test → Ensure correct electromotive force generation.
🔹 Hall Sensor Test → Verify proper hall sensor function.
🔹 Continuity and Short Circuit Test → Check for open or short circuits.
Diagnostic Tests for BLDC Controllers
🔹 Visual Inspection → Identify visible component damage.
🔹 Power Supply Test → Ensure correct power distribution.
🔹 Signal Integrity Test → Verify control signal integrity.
🔹 Functional Test → Test overall controller functionality.
🔹 Component Testing → Ensure individual component functionality
Performance Tests Post-Repair
🔹 No-Load Test → Assess motor performance without load.
🔹 Load Test → Evaluate motor performance under various loads.
🔹 Efficiency Test → Determine motor efficiency.
🔹 Temperature Rise Test → Ensure safe operating temperatures.
